Evaluation of the coefficients of the fourier series representing a voltage waveform obtained by full rectification of an integral number of sinusoidal cycles followed by an ´off period´ an integral number of cycles in length

The program computes the amplitudes and frequencies of the harmonic analysis of a rectified voltage waveform, as may be caused, for example, by the use of thyristors in load control with integral-cycle triggering. The program is general, in the sense thath the control period (´on´ time + ´off´ time)may be any number of supply periods in length, and the number of ´on´ periods may be any number between unity and that to provide full conduction.
