ABSTRACT:
A digital processor (16) is disclosed for improving the statistical characteristics of nondeterministic random-like binary sequence. The basic elements of the digital processor are a feedback loop comprising a delay (17) and a signal combiner (18) and a subsampler (19). Maximum performance of the digital processor is achieved when a relatively prime relationship exists between number of cells in the delay (17) and ratio of the original signaling rate to the output signaling rate of the subsampler (19). Mathematical analysis is presented for showing that the digital processor improves both the equidistribution of the binary variable and autocorrelation statistic of output signal over the nondeterministic random-like binary signal. A further improvement in statistical properties is obtained by using two digital processors (116 and 121) in serial fashion.
