The error signal from a square
wave should show the
feedback ringing centered on
the zero reference.
A static accuracy difference in
the error signal can be
corrected with reset.
The error signal from a sine
should be a small amplitude
sine waveform that looks like a
rounded square waveform.
The square wave shape of the
error signal represents the
phase lag of the feedback
signal.
