Abstract
A circuit for controlling the random character of a bit flow, including an input shift register receiving the bit flow and having its outputs exploited in parallel, at least one element for comparing at least a partial content of the input register with predetermined patterns, a plurality of counters in a number at most equal to the number of predetermined patterns, and an element for detecting the exceeding of at least one threshold by one of the counters, the result of this detection conditioning the state of a word or bit indicative of the random or non-random character of the bit flow.
