What is Understanding Amplitude Modulation Basics about?
1) Amplitude modulation (AM) is used to transmit information signals by varying the amplitude of a carrier wave according to the instantaneous amplitude of the message signal. 2) In AM, the carrier signal is multiplied by the modulating baseband signal, resulting in sidebands at frequencies fc±fm around the carrier frequency fc. 3) Demodulation methods for extracting the original baseband signal include envelope detection and synchronous (coherent) detection using a local oscillator signal synchronized to
