Patent ID: 7225096

Claim:
A method of controlling an asymmetric waveform generated by an asymmetric waveform generator as a combination of two sinusoidal waves having respective frequencies that differ from each other by a factor of two, the method comprising the steps of: sampling the generated asymmetric waveform to obtain a set of data points that is indicative of the generated asymmetric waveform; arranging the sampled data points in an order according to magnitude; comparing the arranged sampled data points to template data relating to a desired asymmetric waveform; in dependence upon the comparison, determining a correction to the generated asymmetric waveform, the determined correction for adjusting at least one of a phase angle difference between the two sinusoidal waves and an amplitude of at least one of the two sinusoidal waves; and, adjusting LC tuning electronics of the asymmetric waveform generator in dependence upon the determined correction, so as to control the asymmetric waveform being generated thereby.
