Q. Assertion FM broadcast is preferred over AM broadcast.
Reason Process of combining the message signals with carrier wave is called demodulation.

Communication Systems

Solution:

In AM modulation, the amplitude of the carrier signal varies in accordance with the information signal. AM signals are noisily because electrical noise signals significantly affect this. In FM modulation, amplitude of carrier wave is fixed while its frequency is changing. FM gives better quality transmission. It is preffered for transmission of music. Demodulation is the process in which the original modulating voltage is recovered from the modulated wave.
