Distinguish between amplitude modulation and frequency modulation.

Text Solution

Verified by Experts

In amplitude modulation, the amplitude of
modulated (carrier)wave changes in accordance
with amplitude of signal wave.
In frequency modulation, the frequency of
modulated (carrier)wave, changes in accordance
with the frequency of signal wave.

    What is frequency modulation ?

    Both amplitude modulation (AM) and frequency modulation (FM) are used for radio broadcasting. The amplitude of the high frequency carrier wave is varied or modulated in accordance with the variations in the amplitude of the audio signals that are to be transmitted, in te process of amplitude modulation in frequency modulation te amplitude of the carrier remains constant but its frequency is varied inn accordance withh the audio signal. Reception with AM signals is in general is affected by interference of various kinds ad elaborated equipment is required for FM broadcast. A radio frequency carrier wave can be modulated using a-
