Abstract
PURPOSE:To easily obtain a random signal by delaying a timing signal in accordance with the output of a random number generating circuit. CONSTITUTION:When a start signal t3 is inputted, a timing generating circuit 1 generates timing signals t2 and t1. Every time the timing signal t2 is inputted, a random number generating circuit 2 generates and sends n-bit random numbers ar0-arn-1 to a counter 3a. The counter 3a and a gate 36 form a delay circuit; every time the timing signal t1 is inputted, a random number is set and when a clock signal phi is counted down until the contents reach 0, an output tr is generated. The delay time from the input of the timing signal t1 to the generation of the output tr varies with the random number, so a random number is obtained.
