Abstract

A method and a circuit for standardizing a noise source providing an initial bit flow, including dividing the initial bit flow into bit words of identical lengths, and assigning an output state according to the states of the bits of the current word and to a pre-established assignment rule, the assignment rule being inverted according to the occurrence, in the initial bit flow, of words, all the bits of which have identical states.
