Phase shift keying (PSK) is a form of frequency modulation implemented in this SPICE simulation with two center tapped transformers. The carrier phase changes from 0–180 each time the modulating data signal changes from 0 to 1, or 1 to 0. The instantaneous value for a PSK signal is νc (t) = Ec cos(2π fc t + θ(t)) Volt.
