In communications systems and in some automatic control systems, the information to be transmitted is first impressed upon a periodic wave called a carrier. Channel tuning is easily accomplished with the use of front panel channel updown push buttons. The carrier frequency should fall on one side of resonant frequency and the entire frequencies should fall on linear region of transfer curve of tuned circuit. Demodulate definition is to extract the information from a modulated signal. Therefore, this chapter begins with a discussion of quadrature phase shift keying qpsk and uses this discussion as a vehicle for development of generic models for quadrature modulation and demodulation.
