Attributes of AC Signals
The most common AC signal is a sine wave. In fact, any periodic signal
can be represented as the sum of different sine waves. The magnitude of
a sine wave is usually specified by its peak, peak-to-peak, or root-mean-
square (RMS) value. All of these measures assume that the waveform
has zero offset voltage.
The peak voltage of a waveform is the maximum absolute value of all
points in the waveform. The peak-to-peak voltage is the difference
between the maximum and minimum. The RMS voltage equals the
standard deviation of all the points in the waveform.
