Patent ID: 6983407

Claim:
A method for controlling the weight of a pseudorandom output pattern generated by an electronic circuit, comprising the steps of: using a plurality of pseudorandom pattern generators (PRPGs) to provide respective sequences of pseudorandom bit-patterns, each of said PRPGs having a predetermined length corresponding to a bit count of an initial state, a predetermined loop count corresponding to a length of a pseudorandom bit-pattern that is repeated indefinitely; feeding an output from each of said PRPGs to a corresponding input of a common logical OR-gate; and initialising a selected subset of said PRPGs with a random-state, a zero-state or a weight-state in order to generate a weighting pattern comprising a pseudorandom bit-pattern, a zero-pattern or a weight-pattern, respectively, whereby the output of said logical OR-gate provides an output pattern reflecting said weighting pattern.
