Abstract: A pseudo-random number generator produces a substantially Gaussian distribution of output numbers from a succession of uniform random numbers. In each cycle uniform random numbers are produced and applied to an adder operative to form cumulative sums. A counter is responsive to carry signals from the adder and the outputs of the adder and counter are combined to form an output pseudo-random number. The number of permitted adding operations is preset.
