Claim Text:
1. A digital system for generating a random number, comprising: a plurality of digital information sources, each digital information source comprising a characteristic, wherein the characteristic of each digital information source differs from the characteristic of any other digital information source, wherein at least one of the digital information sources includes a first clock source, a second clock source, a pseudo random number generator, and a sampling device, wherein the pseudo random number generator is configured to generate a pseudo random number responsive to the first clock source, and output a signal to the sampling device, wherein the second clock source is input into the sampling device and causes the sampling device to output a sampled version of the signal output from the pseudo random number generator; one or more second sampling devices coupled to each of the plurality of digital information sources, wherein the one or more second sampling devices sample the sampled version of the signal output from the pseudo random number generator for each of the plurality of digital information sources at one or more sampling intervals; and wherein a sample value is captured from each of the digital information sources, including the sampled version of the signal output from the pseudo random number generator by the one or more second sampling devices coupled thereto at the one or more sampling intervals, and an output is determined based on the sample values, the output being representative of a substantially random number.
