WebMar 20, 2024 · Incoming signal ---> low pass filter (removes the carrier wave)= modulated signal. I would like to know why the former is stated rather than the latter and the benefits of it. I suppose the incoming signal can include noise that could somewhat alter the signal therefore multiplying by a wave of same frequency can help, but I'm not too sure ... Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in which either the frequency of the carrier wav…
