Abstract: In a random error signal generator, an M-sequence generation circuit outputs, in parallel, pieces of bit data stored in each register, a first generation circuit sequentially outputs first reference values C which are changed by a predetermined value in response to clocks, a second generation circuit outputs a second reference value D which is shifted from the first reference value C by a range value E which is determined depending on an error rate p. A comparison and determination unit outputs random error signals to be error bits when a numeric value A of the bit data output exists between the first and second reference values C, D. The random error signal has the error rate p, the number of times of error occurrences follows Poisson distribution, and a distribution of adjacent error occurrence intervals follows a geometric distribution.

Abstract: A degree of conformity of error distribution of a digital signal to the Poisson distribution is quantitatively determined.

Further, the number of times of occurrence of each measurement value is calculated, a Poisson distribution function is calculated, and a degree of a bond between the Poisson distribution and the distribution of the number of times of occurrence is determined by using the chi-square goodness-of-fit test method.
