Question

Which of the following devices is associated with the reception of radio signals? a. transmitting antenna b. demodulator c. oscillator d. microphone

What is the True Answer . I need the correct answer

Answer 1

transmitting antenna is the answer

Answer 2

The answer is D. Microphone converts sound waves to electrical signals. The microphone has an aperture that vibrates with sound waves. The aperture is attached to a thin coil of wires that is wound around a magnet. Therefore, as the aperture moves, so does the coil of wires. An electric current is consequently induced through magnetic induction.
