Quadrature Amplitude Modulation (qam) Is?

1.	Quadrature Amplitude Modulation (qam) Is?
Answer» The modulation scheme Quadrature Amplitude Modulation (QAM) ENABLES same bandwidth USED for transmission of two DSB-SC signals. It is also known as Bandwidth Conservation scheme. However it needs SYNCHRONOUS DETECTION so it needs an additional SYSTEM for generation of carrier. Also known as Quadrature Carrier Multiplexing, the scheme is used in color television. The modulation scheme Quadrature Amplitude Modulation (QAM) enables same bandwidth used for transmission of two DSB-SC signals. It is also known as Bandwidth Conservation scheme. However it needs synchronous detection so it needs an additional system for generation of carrier. Also known as Quadrature Carrier Multiplexing, the scheme is used in color television.
