Psuedo noise generator

摘要

A pseudo noise generator includes a first arbitrary random number generator that generates two groups of first random number signals respectively corresponding to pre-divided Amplitude Probability Distributions, which are obtained by pre-dividing a specified Amplitude Probability Distribution into two parts at a specified level. A second arbitrary random number generator generates two groups of second random number signals respectively defined by a specified Pulse Duration Distribution and a specified Pulse Spacing Distribution at said specified level. One of the two groups of first random number signals are selected in accordance with the specified Pulse Duration Distribution and the specified Pulse Spacing Distribution defined at said specified level. The selected signals are converted, by a D/A converter, to pseudo noise of analog value in accordance with the Amplitude Probability Distribution, the specified Pulse Duration Distribution and the specified Pulse Spacing Distribution at the specified level.
