ABSTRACT:
This generator generates COS(w.sub.o + w.sub.m)t, SIN(w.sub.o + w.sub.m)t, COS(w.sub.o - w.sub.m)t and SIN(w.sub.o - w.sub.m)t square wave waveforms. This is accomplished by inserting into a carrier square wave clock pulse stream one pulse with the cooperation of a modulation square wave clock in a first signal channel and by deleting from the carrier square wave clock pulse stream one pulse with the cooperation of the modulation square wave clock in a second signal channel. The resultant pulse stream in the first signal channel is suitably divided in a first binary divider and then further divided by a factor of two in a second binary divider to generate the COS(w.sub.o + w.sub.m)t waveform. The complement of the output waveform of the first binary divider is further divided by a factor of two in a third binary divider to generate the SIN(w.sub.o + w.sub.m)t waveform. The resultant pulse stream in the second signal channel is similarly operated on to generate the COS(w.sub.o - w.sub.m)t and SIN(w.sub.o - w.sub.m)t waveforms.
