Abstract
Abstract An improved high speed word generator (30) which includes a white noise generator (12) for providing first and second bits and exclusive or (XOR) means (32) for providing an output signal which is the exclusive or of said first and second bits. In an alternative embodiment, the invention provides an improved N-bit high speed word generator including noise generator means for providing N bits, either through N one bit noise generators or one one bit noise generator and means for storing the output thereof, and exclusive or (XOR) means for providing M stages of N output signals the first stage of which provides N output signals each of which is the exclusive or of two of said bits and the subsequent stages of which provide N output signals each of which is the exclusive or of the output of the previous stage and an output of said noise generator means.
