Question

suppose the microphone on an am radio is not working properly. which best explains how this will affect the process of amplitude modulation? the frequency of the carrier wave will be modified instead of the amplitude. sound waves will not be transformed into electrical signals. electrical signals will not be transformed into sound waves. the pulse of the carrier wave will be modified instead of the amplitude.

Explanation:

The microphone in an AM radio converts sound waves into electrical signals. If it's not working, sound waves won't be transformed into the electrical signals needed for amplitude - modulation.

Answer:

Sound waves will not be transformed into electrical signals.
