Quadrature Amplitude Modlation (QAM): Explained

Описание к видео Quadrature Amplitude Modlation (QAM): Explained

Quadrature Amplitude Modulation (QAM) is used to send large amounts of data by modulating the amplitude of two independent quadrature carrier waves onto a higher frequency carrier wave.
Since these carrier waves are in quadrature they can be coherently demodulated to obtain the independent amplitudes.

QAM allows for extremely large data rates across relatively small bandwiths.
