Abstract: A wideband digital pseudo-gaussian noise generator is disclosed. It includes two feedback shift registers which provide maximal length pseudo noise sequences. Selected stages of the two registers are fed as inputs to 30 exclusive-OR gates, the stages being selected so that their outputs represent distinct phase shifts of a product sequence. The outputs of the gates are summed to provide the generator''s output which approximates gaussian noise over a useful bandwidth of 10MHz.
