PSK Demodulator with Center Tapped Transformers

Description

SPICE simulation of a PSK demodulator. The PSK demodulator contains balanced modulators for recovering data from the PSK signal by multiplying the bandpass PSK signal by an identical carrier. The local oscillator can have errors in frequency and phase placed to simulate the non-coherent conditions. The recovered data output signal from the center-tapped transformer uses a low-pass filter to remove unwanted high-frequency components.
