Singletone amplitude modulation ________(a) consists of only one frequency component(b) contains a large number of frequency components(c) contains no frequency components(d) contains infinite number of frequency componentsThe question was asked in final exam.Question is taken from Single Tone Modulation in chapter Amplitude Modulation of Analog Communications

Answer»

Right OPTION is (a) CONSISTS of only ONE frequency component

The best I can explain: Single tone modulation consists of only one frequency component in the baseband or message signal. Thus, modulation of carrier wave is done by a single frequency component only.
