A direct-conversion receiver with a full digital logic FSK demodulator is presented. It is developed from the quadricorrelator which is known as a frequency detector. We show that the performance of the receiver converges to that of the analog quadricorrelator receiver as the number of mixing axes increases, and obtain the optimum filter bandwidth by computer simulation.
