Amplitude modulation—which of course is the origin of the term “AM radio”—varies the amplitude of the carrier according to the instantaneous value of the baseband signal. The Math The mathematical relationship for amplitude modulation is simple and intuitive: you multiply the carrier by the baseband signal.
Amplitude modulation (AM) is a technique used to encode information in a carrier wave by varying its amplitude. This method allows for the transmission of audio, video, or other data over long distances while maintaining the integrity of the original signal. By changing the amplitude of the carrier wave in proportion to the information signal, AM creates variations that can be analyzed spectrally, revealing insights into non-stationary signals and their frequency components.
