Abstract
PURPOSE:To suppress an unrequired signal with simple constitution, by clipping some of signals when predicting the signal in case of controlling an input signal based on the remainder of the input signal for a predicted value. CONSTITUTION:Prediction is performed by a predictor 7 by finding the remainder of the a predicted signal and an input acoustic signal based on an acoustic signal supplied to an input terminal 1, supplying the signal of the remainder to a clipping circuit 5 by using the signal in which the predicted signal is added on clipped output. By clipping the some of signals at the time of performing the prediction, it is possible to discriminate an external noise with especially high incongruity accurately, and to suppress the external noise satisfactorily.
