ABSTRACT:
A transient signal processing circuit is disclosed which includes a signal input, an adjustable threshold detector for selecting from the signal input a signal portion having at least a minimum amplitude, a peak value detector connected to the threshold detector for providing an output when the signal portion reaches a maximum amplitude, a monostable multivibrator connected to the peak value detector to introduce a time delay and thereby allow the output to stabilize, a sample and hold circuit connected to the multivibrator to record the value of the maximum amplitude, and a clock connected to the multivibrator to indicate the time at which the maximum amplitude was attained.
