Study Notes
Analog-to-Digital (A/D) Conversion
- The A/D converter converts analog signals into digital signals.
Digital-to-Analog (D/A) Conversion
- The D/A converter converts digital signals into analog signals.
Transducer Function
- The transducer converts physical parameters (e.g., temperature, pressure, sound) into analog electrical signals.
Analog Voltage Expression
- In binary, an analog voltage is expressed as a series of 0s and 1s, with each digit (or bit) representing a specific voltage level.
Op-Amp Function in D/A Conversion
- The op-amp (operational amplifier) amplifies the output voltage of the D/A converter to produce the desired analog signal.
Transducer Primary Function
- The primary function of the transducer is to convert physical parameters into analog electrical signals, which can then be converted into digital signals by an A/D converter.
3-Bit Binary System
- In a 3-bit binary system, the binary code 010 represents a specific voltage level (e.g., 2V, 3V, etc.).
Op-Amp Role in D/A Conversion
- The op-amp plays a crucial role in D/A conversion by amplifying the output voltage of the D/A converter to produce the desired analog signal.
A/D Converter Function
- The A/D converter converts analog signals into digital signals.
Analog Signal Examples
- Examples of analog signals mentioned in the text include temperature, pressure, and sound.
