Test Your Knowledge of Electronic and Mass Communication Systems

Overview of Electronic and Mass Communication Systems

• Telecommunication involves the use of electronic machines to convey messages over long distances, including landline telephones, radios, televisions, fax machines, mobile phones, and computers.
• Mass communication is accomplished via mass media, which includes technology capable of sending messages to large numbers of people, for purposes such as entertainment, education, political and religious messages, and news.
• Mass media communication is an essential component of modern marketing due to its ability to reach a wide audience quickly and cost-effectively, create impactful and memorable social messages, influence how people view the world, and shape public opinion.
• The three essential components of communication systems are the transmitter, channel, and receiver, which work together to modulate, transmit, and demodulate the message signal.
• Communication systems can be classified as analogue or digital, depending on whether they communicate data as electronic signals of varying frequency or amplitude, or generate and process data in two states (high and low).
• Communication channels can be wired (e.g. parallel wire, twisted wire, coaxial cable, and optical fibre communication) or wireless (e.g. ground wave, sky wave, space wave, and satellite communication).
• Examples of communication systems include the internet, intranet and extranet, public switched telephone network, and television.
• The information being transmitted can take many forms, such as audio, video, picture, temperature, or pressure.
• The signal is the electromagnetic representation of the information, carried as a single-valued function of time.
• Transducers convert one form of energy to another, such as converting physical variables like pressure, force, and temperature into corresponding electrical signal variations.
• Amplifiers increase the amplitude or strength of the transmitted signal when necessary.
• Modulators superimpose message signals with high frequency and high amplitude carrier waves to create a modulated wave that can be transmitted over long distances.
