ABSTRACT:
The invention includes directing an analog electrical signal through a plurality of discrete time delays in order to sequentially introduce cumulative time delays to the electrical signal. The magnitudes of the electrical signal before and after the introduction of each of the time delays are compared, and a plurality of pulse signals are generated in response to the comparisons. Logic circuitry is responsive to the logic conditions of the pulse signals to generate output signals indicative of the amplitude peaks or slopes of the electrical signal.
