Apparatus and method for generating random numbers

Abstract

If a random number generated by a random-number generator is equal to or greater than a random number having a predetermined amplitude, a high-level comparison result signal is produced to cause an AND gate and an OR gate to apply clock pulses to the random-number generator, which updates the random number. Only random numbers whose amplitude is smaller than the predetermined amplitude are stored in a D-type flip-flop and outputted as generated random numbers. Since random numbers whose amplitude is smaller than the predetermined amplitude are selected from the random numbers that are outputted from the random-number generator, a random-number generating apparatus does not require a processing circuit, and may be of a relatively small circuit scale and can generate random numbers having a desired amplitude at all times and with no amplitude errors.
