Question

Explain The AM and FM radio transmission​

Answer 1

Answer:

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.

In AM, a radio wave is known as the "carrier" or "carrier wave" is modulated in amplitude by the signal that is to be transmitted. In FM, a radio wave is known as the "carrier" or "carrier wave" is modulated in frequency by the signal that is to be transmitted. ... The frequency and phase remain the same.
