1. A method for sampling a signal during each of a plurality of successive time periods of equal duration comprising the steps of:

  • generating a plurality of pseudo random pulses of equal duration with successive ones of said pseudo random pulses occurring during successive ones of said successive time periods of equal duration; and

    sampling the signal during each of said pseudo random pulses, the period of a pseudo random pulse during which the sampling occurs being known as a sampling interval, each sampling interval occurring at an essentially random time within said time period, whereby harmonics at the time period recurrence frequency are substantially lessened.
