Pseudo-random binary data flow generator - has parallel binary generators feeding output selector varying flow probability

摘要

A generator provides a stream of binary data where the probability of a 1 or a 0 appearing is equal, the stream sequence not being repeated within a length of time much greater than that required for its application. The psuedo random stream if intended esp. for testing data transmission systems and equipment where error detection is required. The generator has n parallel input circuits synchronised from a clock source at some frequency F' delivering trains of binary signals. These are processed by logic and output circuits for each stream and fed via a switch which enables the overall stream probability to be varied at the generator output point.
