Abstract

PURPOSE: To make it possible to use one signal selecting circuit as a signal selecting circuit for n-bits of a selective signal and as two signal selecting circuits for n-1 selective signal bits.
CONSTITUTION: Selective signals a0, a1...an-1 are displayed in binary notation and divided into two groups (A and B) so that they will have Hamming distances, not less than two, one another in one group; selective signals in group A are led to the input of AND circuit 1 to which selected signals b1Wb6 are inputted, and those in group B to the input of AND circuit 1 to which selected signals b4Wb6 are inputted. Then, control signal C is held at "1" and output f0 or OR circuit 2 is used to make selective signals serve as n-bit signals, and control signal C is held at "0" and output f1 obtained by using a0Wan-3 and an-1 as selective signals and output f2 by using a0Wan-3 and an-2 are used to obtain two n-1-bit circuits.
