A method for generating sequences that approximate binary random sequences with the probability of a 1 equal to 1/4 is described. These are called sequences. sequences are generated by clocking a sequence generator at the l's of a sequence. The sequence is 1 when the generator output makes a transition and is 0 otherwise. It is shown that sequences have period if the sequence generators have period . The density of l's is shown to approach 1/4 for large . It is shown that the normalized out-of-phase pulse-coincidence autocorrelation function can never exceed 1/2 or be less than 1/4 and is 1/4 most of the time for large .
