Introduction to PSK Demodulation Phase Shift Keying (PSK) is a digital modulation technique where the phase of a carrier signal is varied in accordance with the binary data. PSK is widely used in modern communication systems due to its bandwidth …
How is the 90˚ phase shift implemented? There are two methods that we will discuss here to implement a 90-degree phase shift inside a receiver. The first method is the RC-CR network and the second method is Quadrature downconversion. In …
