Method and apparatus for generating random signals
First Claim
Patent Images
1. A method of generating a random binary waveform containing events which occur at random intervals, the method comprising:
- deriving, from a physical noise source, a first preliminary signal containing first events occurring asynchronously and at random intervals; and
multiplying the first preliminary signal with at least one further preliminary signal containing further events, said at least one further preliminary signal being a deterministic signal, so as to intersperse the first and further events;
wherein the physical noise source produces a non-deterministic output.

Abstract
A random binary signal is generated using a plurality of noise sources, each of which defines events occurring at random intervals, the outputs of the sources being combined in such a way that the events are interspersed in the resultant signal.

10. Apparatus for generating a random binary waveform containing events which occur at random intervals, the apparatus comprising:
-
a physical noise source producing a random output signal; means for deriving, from said random output signal, a first preliminary signal containing first events occurring asynchronously at random intervals; means for providing at least one further preliminary signal containing further events occurring at said random intervals, said further preliminary signal being a deterministic signal; and means for multiplying the first preliminary signal and said at least one further preliminary signal so as to produce a random binary waveform in which said first and further events are interspersed; wherein the physical noise source produces a non-deterministic output. - View Dependent Claims (11)
