A message signal of frequency \omega _m is superposed on a carrier wave of frequency \omega _c to get an amplitude modulated wave (AM). The frequency of the AM wave will be

(a) \omega _m

(b) \omega _c

(c) \frac{\omega _c +\omega _m}{2}

(d) \frac{\omega _c -\omega _m}{2}

Answers (1)

Since the frequencies of both the carrier wave and the amplitude-modulated wave are similar, the frequency of the AM wave would be (b) ωc
