ABSTRACT:
A waveform instability circuit provides a voltage/time window for monitoring a known unipolar waveshape or pulse. The voltage/time window is adjustable in dimension and in location along the wavefront. This allows a particularly significant portion of the pulse to be continuously monitored for accuracy or for various segments of the pulse to be selectively monitored merely by repositioning the window. Three voltage comparators are used to determine the reference voltage and voltage window limits. Monostable multivibrators responsive to the reference voltage control the time window limits and logic gates provide the determination of coincidence or anticoincidence of the input waveform section being considered with the window limits.
