ABSTRACT:
A frequency generator for generating a large number of closely and evenly spaced frequencies over a large bandwidth including a first digitally controlled oscillator and a second digitally controlled oscillator, and a combiner for mixing the frequencies from said first and second digitally controlled oscillators, wherein the sampling rate of the digitally controlled oscillators differs by a small predetermined amount. Switching speed is extremely rapid.
