A method of controlling an asymmetric waveform generated as a combination of two sinusoidal waves having a frequency that differs by a factor of two, the method including the steps of sampling a generated asymmetric waveform to obtain a set of data points, the set of data points being indicative of the generated asymmetric waveform, arranging the sampled data points in an order according to magnitude, and comparing to template data relating to a desired asymmetric waveform. In dependence upon the comparison, a correction to the generated asymmetric waveform is determined.
