Abstract

PURPOSE:To make it possible to attain the abnormal oscillation prevention of multiplexed data without any error, by interposing a path delay circuit for a control signal in a feedback digital filter of multiple constitution that prevents an abormal oscillation phenomenon. CONSTITUTION:While overflow detecting circuit 14 detects the input signal of delay register R1 at the initial stage of delay register 12, i.e. the overflow of the output signal of subtracting circuit 3, its overflow detection signal is delayed by delay circuit 17 by a certain time and then supplied as a control signal to conversion correcting circuit 16. Consequently, circuit 16 converts and corrects the output signal of register 12, namely, the output signal of final-stage delay register RN. Therefore, abnormal oscillation prevention can be attained as to multiplexed data without any error.
