Ltd. - 24 / 457- Basic Terminology Introduction To Basic Electronics Electricity  The flow of electrons through conductor.  It is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and the flow of electrical current.  In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves. Electronics  The flow and control of electrons.  It deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits and associated passive interconnection technologies. The nonlinear behavior of active components and their ability to control electron flows makes amplification of weak signals possible  Electronics is widely used in information processing, telecommunications and signal processing. The ability of electronic devices to act as switches makes digital information processing possible. Samsung India Electronics Pvt. Ltd. - 25 / 457- Basic Terminology Introduction To Basic Electronics What is Ohm's Law? Ohm's Law is made from 3 mathematical equations that shows the relationship between electric voltage, current and resistance. What is voltage?  An analogy would be a huge water tank filled with thousands of gallons of water high on a hill.  The difference between the pressure of water in the tank and the water that comes out of a pipe connected at the bottom leading to a tap is determined by the size of the pipe and the size of the outlet of the tap. This difference of pressure between the two can be thought of as potential Voltage. What is current?  An analogy would be the amount of flow determined by the pressure (voltage) of the water through the pipes leading to a tap.  The term current refers to the quantity, volume or intensity of electrical flow, as opposed to voltage, which refers to the force or "pressure" causing the current flow. What is resistance?  An analogy would be the size of the water pipes and the size of the tap.  The larger the pipe and the tap, the more water that comes out (less resistance). The smaller the pipe and tap, the less water that comes out (more resistance).  This can be thought of as resistance to the flow of the water current. Samsung India Electronics Pvt. Ltd. - 26 / 457- Basic Terminology Introduction To Basic Electronics  All three of these: Voltage, Current and Resistance directly interact in Ohm's law.  Change in any two of them affects the third.  Ohm's law can be stated as a mathematical equation, all derived from the same principle.  In the following equations, i. V is voltage measured in volts (the size of the water tank), I is current measured in amperes (related to the pressure (Voltage) of water thru the pipes and faucet) and R is resistance measured in ohms as related to the size of the pipes and tap: ii. V = I x R (Voltage = Current multiplied by Resistance) iii. R = V / I (Resistance = Voltage divided by Current) iv. I = V / R (Current = Voltage Divided by Resistance)  Knowing any two of the values of a circuit, one can determine (calculate) the third, using Ohm's Law. Note: Ohm's Law was named after Bavarian mathematician and physicist Georg Ohm. Samsung India Electronics Pvt. Ltd. - 27 / 457- Basic Terminology Introduction To Basic Electronics Series Circuit The first principle to understand about series circuits is that the amount of current is the same through any component in the circuit. This is because there is only one path for electrons to flow in a series circuit and because free electrons flow through conductors like marbles in a tube. The rate of flow (marble speed) at any point in the circuit (tube) at any specific point in time must be equal.  Components in a series circuit share the same current ITotal = I1 = I2 =... In  Total resistance in a series circuit is equal to the sum of the individual resistances RTotal = R1 + R2 +... Rn  Total voltage in a series circuit is equal to the sum of the individual voltage drops VTotal = V1 + V2 +... Vn Samsung India Electronics Pvt. Ltd. - 28 / 457- Basic Terminology Introduction To Basic Electronics Parallel Circuit The first principle about parallel circuits is that the voltage is equal across all components in the circuit. This is because there are only two sets of electrically common points in a parallel circuit and voltage measured between sets of common points must always be the same at any given time.  Components in a parallel circuit share the same voltage VTotal = V1 = V2 =... Vn  Total resistance in a parallel circuit is less than any of the individual resistances RTotal = 1 / (1/R1 + 1/R2 +... 1/Rn)  Total current in a parallel circuit is equal to the sum of the individual branch currents ITotal = I1 + I2 +...

Samsung India Electronics Pvt. Ltd. - 41 / 457- Overview of Technologies Voice Transmission Process How does voice travels from one place to another using mobile phone? To understand voice transmission in detail, first of all, we will learn different parameters which helps voice to travel from one place to another. Sound:  Sound is a vibration that propagates as a typically audible mechanical wave of pressure and displacement through a medium such as air. Frequency:  Frequency is the number of occurrences of a repeating event per unit of time.  Its unit is Hertz (Hz) Audio Signal:  An audio signal is a representation of sound, typically as an electrical voltage.  Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing).  Audio signals may be synthesized directly or may originate at a transducer such as a microphone.  Loudspeakers or headphones convert an electrical audio signal into sound.  Digital representations of audio signals exist in a variety of formats. Samsung India Electronics Pvt. Ltd. - 42 / 457- Overview of Technologies Voice Transmission Process Transducer:  A transducer is a device that converts a signal in one form of energy to another form of energy.  Energy types include (but are not limited to) electrical, mechanical, electromagnetic (including light), chemical, acoustic and thermal energy.  The term transducer commonly implies the use of a sensor/detector.  Any device which converts energy can be considered a transducer.  A sensor (transducer) is used to detect a parameter in one form and report it in another form of energy, often an electrical signal. For example a pressure sensor might detect pressure (a mechanical form of energy) and convert it to electrical signal. Actuator:  An actuator accepts energy and produces movement (action).  The energy supplied to an actuator might be electrical or mechanical.  An electric motor and a loudspeaker are both actuators, converting electrical energy into motion for different purposes. Samsung India Electronics Pvt. Ltd. - 43 / 457- Overview of Technologies Voice Transmission Process Combination Transducers:  Combination Transducers is a single device that detects and creates action.  For example, a typical ultrasonic transducer switches back and forth many times in a second between acting as an actuator to produce ultrasonic waves, and acting as a sensor to detect ultrasonic waves.  Rotating a DC electric motor's rotor will produce electricity and voice-coil speakers can also act as microphones Microphone:  A microphone also called a mic or mike is an acoustic to electric transducer or sensor that converts sound in air into an electrical signal.  Microphones are used in many applications such as telephones, tape recorders, radio & television broadcasting also used in computers for recording voice and speech recognition,  Most microphones today use electromagnetic induction (dynamic microphone), capacitance change (condenser microphone) or piezoelectric generation to produce an electrical signal from air pressure variations.  Microphones typically need to be connected to a preamplifier before the signal can be amplified with an audio power amplifier or recorder. Samsung India Electronics Pvt. Ltd. - 44 / 457- Overview of Technologies Voice Transmission Process Loud Speaker:  A loudspeaker or speaker is an electro acoustic transducer that produces sound in response to an electrical audio signal input.  Speakers convert electrical signals into audible signals.  Non-electrical loudspeakers were developed as accessories to telephone systems but electronic amplification by vacuum tube made loudspeakers more useful.  The most popular speaker used today is the dynamic speaker.  The dynamic speaker operates on the same basic principle as a dynamic microphone. Signal:  A typical role for signals is in signal processing.  A common example is signal transmission between different locations.  The embodiment of a signal in electrical form is made by a transducer that converts the signal from its original form to a waveform expressed as a current (I) or a voltage (V), or an electromagnetic waveform, for example, an optical signal or radio transmission.  Once expressed as an electronic signal, the signal is available for further processing by electrical devices such as electronic amplifiers and electronic filters and can be transmitted to a remote location by electronic transmitters and received using electronic receivers. Samsung India Electronics Pvt. Ltd. - 45 / 457- Overview of Technologies Voice Transmission Process Analog Signal:  An analog or analogue signal is any continuous signal for which the time varying feature (variable) of the signal is a representation of some other time varying quantity, i.e., analogous to another time varying signal.  For example, in an analog audio signal, the instantaneous voltage of the signal varies continuously with the pressure of the sound waves.  Any information may be conveyed by an analog signal.  Often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position or pressure.  The physical variable is converted to an analog signal by a transducer. For example, in sound recording, fluctuations in air pressure (sound) strike the diaphragm of a microphone which induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone or the voltage produced by a condenser microphone.  The voltage or the current is said to be an "analog" of the sound.  An analog signal has a theoretically infinite resolution. In practice an analog signal is subject to electronic noise and distortion introduced by communication channels and signal processing operations Samsung India Electronics Pvt. Ltd. - 46 / 457- Overview of Technologies Voice Transmission Process Digital Signal:  A digital signal refers to an electrical signal that is converted into a pattern of bits.  Unlike an analog signal, which is a continuous signal that contains time-varying quantities, a digital signal has a discrete value at each sampling point.  The precision of the signal is determined by how many samples are recorded per unit of time.  A digital signal is easily represented by a computer because each sample can be defined with a series of bits that are either in the state 1 (on) or 0 (off).  Digital signals can be compressed and can include additional information for error correction. Electronic Processor:  An electronic processor is used to convert any data into meaningful output.  Information can easily be discarded by the system but adding information takes effort.  The electronic processor can add information only in a rule based fashion.  Up sampling the data or converting to a more feature rich format does not add information; it merely makes room for that addition which usually a human must do.  By storing data electronically, the chances of data loss are greatly lowered and it is easier to perform data mining and other conversions.  Data stored in an electronic format can be quickly modified and analyzed. Samsung India Electronics Pvt. Ltd. - 47 / 457- Overview of Technologies Voice Transmission Process Digital to Analog Converter (DAC) and Analog to Digital Converter (ADC):  Electronic equipment is frequently used in different fields such as communication, transportation, entertainment, etc.  Analog to Digital Converter (ADC) and Digital to Analog Converter (DAC) are very important components in electronic equipment.  Since most real world signals are analog, these two converting interfaces are necessary to allow digital electronic equipments to process the analog signals.  ADC converts the analog signal collected by audio input equipment such as a microphone, into a digital signal that can be processed by computer.  The computer may add sound effect such as echo and adjust the tempo and pitch of the music. DAC converts the processed digital signal back into the analog signal that is used by audio output equipment such as a speaker.  In electronics, an Analog to Digital Converter (ADC) is a device for converting an analog signal (current, voltage etc.) to a digital code, usually binary.  In the real world, most of the signals sensed and processed by humans are analog signals.  Analog to Digital conversion is the primary means by which analog signal are converted into digital data that can be processed by computers for various purposes. Samsung India Electronics Pvt. Ltd. - 48 / 457- Overview of Technologies Voice Transmission Process Power Amplifier:  A power amplifier is a type of electronic amplifier used to convert a low power radio frequency signal into a larger signal of significant power, typically for driving the antenna of a transmitter.  It is usually optimized to have high efficiency, high output power (1dB) compression, good return loss on the input and output, good gain and optimum heat dissipation.  The basic applications of the RF (radio frequency) power amplifier include driving to another high power source and driving a transmitting antenna by exciting microwave cavity resonators.  Among these applications, driving transmitter antennas is most well known. Frequency Converter  A frequency converter is a power conversion device.  The frequency converter converts a basic fixed frequency, fixed voltage sine wave power (line power) to a variable-frequency, variable-voltage output.  It usually consists of a local oscillator and frequency mixer (analog multiplier) that generates sum and difference frequencies from the input and local oscillator, of which one (the Intermediate frequency) will be required for further amplification while the others are filtered out.
