Strong Buzz Example Waveforms
and
show the output waveform (trace C1 and C2), the differential output (trace Math),
and the acceleration profile (trace C4) for the buzz waveform.
displays the waveform in auto-
resonance mode while
displays the same waveform in open-loop mode. Auto-resonance mode
allows the acceleration profile to have a higher peak acceleration at a lower V
RMS
voltage.
