The rms amplitude is defined as the square root of the average of the square of the signal. For a periodic wave function, the time average is the integral over one period, divided by the period. For a sinusoidal voltage given by V = Vp sin t, it can be shown that Vrms = Vp / 2. How are the rms and peak voltages related for the square wave shown in Fig. 33-28?
