Abstract

PURPOSE:To simplify the constitution, by processing an input digital signal by dividing it into plural bit sequence parts whose number of bits is less than the number of bits of a multiplier. CONSTITUTION:Hihg-order 8 bits of an input digital signal Xn consisting of 16 bits are held by a holding circuit 14, and are applied to a multiplier and adder 17 as they are. Also, low-order 8 bits are held by a holding circuit 15, and 7 bits except LSB among them are applied to a signal processor 16. In the signal processor 16, in addition to 7 bits from the holding circuit 15, ''0'' is inserted as MSB, they are converted to a signal of total 8 bits, and are applied to the multiplier and adde 17. The multiplier and adder 17 multiplies and adds the signals from the holding circuit and the signal processor 16, and a coefficient from a coefficient device 18, respectively and its results are held by holding circuits 19, 20, respectively. An output signal of the holding circuit 20 is shifted to the right by 7 bits by a signal processor 21, and after that is added with an output signal of the holding circuit 19 by an adder 22, and is outputted from an output terminal 23 as an output digital signal yn displayed by two's complement.
