Amplitude Modulation Theory: In Amplitude Modulation Theory, the amplitude of a carrier signal is varied by the modulating voltage, whose frequency is invariably lower than that of the carrier. In practice, the carrier may be high-frequency (HF) while the modulation is … (Read More)

Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates such high powers that its prime requirement is efficiency, so quite … (Read More)
