The invention detects pulses, and, in response thereto, generates ramp functions with amplitudes corresponding to the interarrival times between successive pulses. These amplitudes are measured, and the occurrence of identical amplitudes are accumulated in corresponding memory locations, each of which has an address corresponding to a particular interarrival time. The resultant memory contents define a population distribution of interarrival times which is an exponential decay function of interarrival time. Interarrival times exceeding a preselected value are disregarded.
