Abstract

PURPOSE:To use effectively the capacity of IC memory by sending the memory output to a buffer register and feeding back a part of this output to a selector, which is provided in the input side of the memory, to suit a digital filter to multiplexing. CONSTITUTION:A digital filter consists of adder 1, multiplier 2 and deley circuit 3; and when input signal en is inputted to input terminal 4, the signal processing is performed to obtain digital signal vn from output terminal 5. By this delay circuit 3, the output of memory 16 is sent to buffer registers 17 and 18 and a part of the output of register 17 is fed back to selector 15 which is provided in the input side of memory 16. As a result, the digital filter can be suited to multiplexing, and the capacity of IC memory can be used effectively.
