Abstract: A pseudo-random number sequence output unit responsive to s (1?s) number of prescribed positive integers q1, q2, . . . , qs, a prescribed real impulse constant r (?1<r<1), and a prescribed non-zero real constant C for outputting a pseudo-random number sequence of length N (1?N), which output unit includes: an input acceptance section that accepts input of s (1?s) number of real number sequence initial values Y1, Y2, . . . , Ys (?1<Y1<1, ?1<Y2<1, . . . , ?1 Ys<1), and s number of integer parameters p1, p2, . . . , ps (2?p1, 2?p2, . . . 2?ps) for which q1 mod p1?0, q2 mod p2?0 . . . , qs mod ps?0 respectively hold with respect to the prescribed positive integers q1, q2 . . . qs; a calculation section that uses the prescribed real impulse constant r, the prescribed non-zero real constant C, the sequence initial values Y1, Y2, . . . , Ys, the integer parameters p1, p2, . . . , ps, the prescribed positive integers q1, q2, . . .
