Abstract: In a waveform generator, a repetitive non-linear waveform is generated by varying the number supplied to a pulse reduction circuit during the repetition period. Consequently, the pulse reduction circuit supplies a number of desired output pulses, which number varies in time corresponding to the varying number. For example, when a lower number is inputted to the pulse reduction circuit during a sub-period of the repetition period, a corresponding lower number of output pulses will be generated. Consequently, a lower number of increment values will be summed or integrated during this sub-period and the waveform changes less steeply.

Abstract: In a waveform generator according to the first aspect of the invention, a repetitive non-linear waveform is generated by varying the number supplied to the pulse reduction circuit during the repetition period. Consequently, the pulse reduction circuit supplies a number of desired output pulses, which number varies in time corresponding to the varying number. For example, when a lower number is inputted to the pulse reduction circuit during a sub-period of the repetition period, a corresponding lower number of output pulses will be generated. Consequently, a lower number of increment values will be summed or integrated during this sub-period and the waveform changes less steeply.
