What device reproduces the information signal received by the antenna and selects the desired frequency?

• A. Amplifier
• B. Transmitter
• C. Receiver
• D. Speaker

Answer: (C)

The device that reproduces the information signal received by the antenna and selects the desired frequency is the receiver. A receiver's primary function is to pick up radio signals from an antenna, amplify them, and then demodulate the signals to extract the information being transmitted, such as audio or data. In avionics, receivers are vital components that enable communication between the aircraft and ground stations or other aircraft. They filter and select the specific frequency of interest, allowing the received signals to be processed accurately. This filtering and frequency selection ensure that only the desired signals are amplified and converted into usable information, which could include voice communications or navigational data. The other devices mentioned have different functions: an amplifier boosts signal strength but does not demodulate or filter frequencies; a transmitter sends signals out but does not receive them; and a speaker converts electrical signals into sound but does not handle signal reception or frequency selection. Thus, the specialized role of a receiver makes it the correct answer to this question.
