Abstract

A method of sampling accurately the instantaneous content of a high speed counter without interrupting the counting process is provided. The method is applicable even when the higher order digits of the counter are constructed by slower switching circuits configured in either a synchronous or ripple-through arrangement. The switching and carry propagation times of these higher order counters need not be shorter than the time between successive events being counted. Sampling of the contents may be made repeatedly in the interim without affecting the totality of the final count.
