Question
Frequency components of an AM wave (m = modulation index) areSelect one:a. Lower side band (ωc - ωm) having amplitude mA/2b. Upper side band (ωc + ωm) having amplitude mA/2c. Carrier frequency (ωc ) with amplitude Ad. All of the above
Solution
d. All of the above
An Amplitude Modulated (AM) wave consists of a carrier wave and two sidebands. The carrier frequency (ωc) is the original frequency of the signal before modulation. The lower sideband (ωc - ωm) and the upper sideband (ωc + ωm) are the frequencies produced as a result of the modulation process. The amplitude of the sidebands is mA/2, where m is the modulation index. Therefore, all of the options a, b, and c are correct.
