任意確率分布の乱数発生器

抄録

In a present computer system, in order to obtain an arbitrary probability density distribution, we use uniform random numbers and modify them. It is desired to generate any random numbers by a simple equipment.
In this paper, the authors report on a new probability density function generator utilizing stochastic computer techniques.
The equipment is composed of a stochastic integrator (a simple reversible counter with comparator) with a feedback circuit.
The latter performs the important role in obtaining the desired random numbers and controlling their stochastic parameters.
Theory and circuit diagrams are shown together with the interesting experimental results.
