The switching transient (upper trace) at output of diode bridge when it is turned "on" by the gating voltages (lower traces).

Same as 4(a) except for lower scope sensitivity on upper trace.

Bridge output response (upper trace) to -5V input pulse (lower trace). Bridge turn-on coincides approximately with the -5V to OV transition.
