Measurement of EIS and the photoelectrode film thickness. WebIn pulse-width modulation, the switches are turned on at a constant chopping frequency. The total time of one cycle of the output waveform is constant. The average output voltage is directly proportional to the ON time of the chopper. The ratio of ON time to total time is defined as the duty cycle. It can vary between 0 and 1 or between 0 and 100%.
