With which signal pattern is the RMS reading the same as the average reading?
A) Square wave
B) Nonsymmetric
C) Sine wave
D) None of these

Question

Quizplus · Accepted Answer

The RMS reading of a sine wave is equal to the average reading because the waveform is symmetrical about the zero axis, resulting in the positive and negative values canceling each other out. In contrast, a square wave and nonsymmetric waveform have different RMS and average readings.
