Abstract
A method of generating random numbers comprises: generating a first noise and passing the first noise through a first high pass filter which removes a periodic component contained in the first noise to produce a first noise signal having 1/f characteristic; generating a second noise and passing the second noise through a second high pass filter which removes a periodic component contained in the second noise to produce a second noise signal having 1/f characteristic; supplying the first and second noise signals to a differential circuit to derive a different signal between the first noise signal and said second noise signal; and generating, from the different signal, random numbers which do not have a periodicity due to 1/f characteristics of the first and second noise signals.

A method of generating random numbers comprising the steps of:
- generating a first noise and passing the first noise through a first high pass filter which removes a periodic component contained in the first noise to produce a first noise signal having 1/f characteristic from a first noise generator circuit and;
- generating a second noise and passing the second noise through a second high pass filter which removes a periodic component contained in the second noise to produce a second noise signal having 1/f characteristic from a second noise generator circuit;
- supplying said first and second noise signals having 1/f characteristic to a differential circuit to derive a difference signal between said first noise signal and said second noise signal;
- and
- generating, from said difference signal, random numbers which do not have periodicity due to 1/f characteristics of the first and second noise signals.
