Abstract:
In statistics simulation by means of electronic computers random numbers are used as a factor for contingency. A random number generator introduced here is intended for feeding random numbers to electronic computers. Different from the random number generation by means of software, this machine depends on totally physic probability phenomena and by processing the phenomena generates random numbers. It is expected that problems inherent to software random number generation can be solved by the use of this physic generator.
This article introduces a random number generator, completed by Hitachi to the order of the Statistic Mathematics Institute, which has a transfer speed about 100 times that of similar devices for laboratory use.
