RECURSIVE DIGITAL FILTER Abstract of the Disclosure This invention is designed to prevent a malfunc- tion due to an overflow, in a combinatorial type recursive digital filter whose feedback side is of the second or higher order. The overflow of the output of an arithmetic unit which executes an addition within the filter is detected, whereupon the contents of the shift registers for delay on, at least, the feedback side are reset by an output from the detecting device.
