  It is shown that a random binary process with impulse-like autocorrelation
can be generated by randomizing the length of symbols occurring in a random
Bernoulli process. Such randomization is achieved by random (or judiciously
designed irregular) sampling of the output of a source that supplies a
symmetric random binary waveform. One practical configuration implementing the
proposed technique is a linear-feedback shift register driven by a
spread-period clock generator.
