This patent describes a rate meter type random event counter circuit having a dead time characteristic. Two or more successive random events during a predetermined period of time erroneously generate an event count signal indicative of only a single count, the occurrence of such erroneous single count signals increasing as the frequency of the random events increases. The random event counter circuit includes an active circuit element means having an input responding to event count signals including as a portion thereof the erroneous single count signals, and an output providing a signal having a value intended to indicate the actual rate of the random events. A dead time compensation circuit means for detecting the frequency of the event count signals; and means responsive to the detecting means for non-linearly modifying a transfer function of the active circuit element.
