PURPOSE:To realize an identification system by a small-scaled hardware, to shorten a converging time, and to reduce a remaining error. CONSTITUTION:Plural adaptive filters 9001-900k connected in parallel can identify an unknown system having one fixed delay and an impulse response constituted of a response waveform part, and exchange a counter control signal and a response waveform part information. The filter 900j transmits whether or not the estimation of the response waveform part is ended to the filter 900j+1 as the counter control signal, and the filter 900j+1 as decides the timing of the start of the adaptive operation according to the supplied counter control signal. Also, information related with the position of the response waveform part is supplied from the filter 900k-1 to the filter 900k, and its own response waveform part is controlled so as to be arranged behind the position of the response waveform part of the filter 900k-1. |
