Amplitude Modulation

Amplitude modulation (AM) is a technique used in electronics most commonly for transmitting information via radio carrier wave. The final modulation consists of three components: carrier, lower side band, and upper side band. Various combinations of these components create various types of AM with different properties for information transfer. Also, modulation depth has a big influence on modulation properties. The carrier signal with amplitude modulation is illustrated in blue while the modulating signal (sine wave) is in orange.
