Quadrature Amplitude Modulation (QAM)
Definition - What does Quadrature Amplitude Modulation (QAM) mean?
Techopedia explains Quadrature Amplitude Modulation (QAM)
QAM combines the two carriers and sends the combined signals in a single transmission to be separated and extracted at the destination. The signals are demodulated, and the data are then extracted from each and recombined to form the original modulating information. Examples of technologies using QAM are the PAL and NTSC television systems, where the different channels, which are provided by QAM, enable the transmission of the components of chroma or color information to TV sets.
