What is the phase shift between the signals?

Phase shift simply means that the two signals are at different points of their cycle at a given time. Phase shift is measured as the angle (in degrees or radians) between two points on a circle at the same time, demonstrating the progress of each wave through its cycle.

What are three basic non-sinusoidal waveforms?

Common nonsinusoidal waveforms: (a) dc; (b) square-wave; (c) triangular; (d) sawtooth; (e) rectified.

Which of the following is a non-sinusoidal waveform?

A non-sinusoidal waveform is typically a periodic oscillation but is neither of these. Some examples are triangle waves, rectangle waves, square waves, trapezoid waves and saw tooth waves.

How can the effective value of a non-sinusoidal wave be determined?

RMS Voltage Equivalent

Graphical Method – which can be used to find the RMS value of any non-sinusoidal time-varying waveform by drawing a number of mid-ordinates onto the waveform. Analytical Method – is a mathematical procedure for finding the effective or RMS value of any periodic voltage or current using calculus.
