use Matlab ONLY to calculate the RMS voltage of a rectangular pulse shaped waveform with a period of 1 ms. The wave should have a minimum peak of 0 V and a maximum peak of 4 V. Calculate the RMS voltage for ON time duty cycles of 20, 50 and 80 percent. Also calculate the RMS voltage for a triangular wave of the same voltage levels (going from 0 to 4 volts and back to 0 volts at the end of the period). 2.828mv
