Abstract
A demodulator for shaped BPSK signals that utilizes switches which have switching control means designed to eliminate unwanted Q channel signal power and unwanted carrier phase error signal power by opening the switches during the phase transition portions of the shaped BPSK signals. The switching control means close the switches during non-transitional portions of the shaped BPSK signals.
