Determine the phase shift between the two sinusoidal voltage

Determine the phase shift between the two sinusoidal voltages of Fig. 7.13.

Solution

In one square wave 90 degree phase shift.

One square wave has five divisions , so each division cover 90/5=18 degrees.

From the figure, there is a difference of four divisions between the zero degree of individual wave. So the total phase shift=4*18=72 degrees.
