Abstract:
1. A digital random noise generator comprising: a first pseudo-random pattern generator circuit for generating first sets of random bit pattern signals; two or more delay devices in a parallel configuration each receiving a trigger input signal and a random bit pattern signal set for generating in response a respective delay output signal in parallel paths, each delay output signal being delayed in time with respect to a respective said trigger signal and functioning as a trigger input signal of a successive delay device of said parallel configuration for commencing operation of a successive delay device in said parallel configuration, a delay time of each delay output signal being determined by said bit pattern set received; an oscillator circuit device associated with a respective delay device for receiving a respective delay output signal therefrom and generating a respective oscillating signal, each oscillator signal being used to generate artificial pseudo-random noise for emulating a real noise environment in an electronic device.
