ADAPTIVE DIGITAL FILTER INCLUDING LOW-PASS FILTER ABSTRACT OF THE DISCLOSURE An adaptive digital filter for estimating a response characteristic of a signal path by monitoring a sampled output signal of the signal path, estimating a predetermined number of filter coefficients which represent the response characteristic of the signal path, and generating an estimated output signal of the signal path using a plurality of successive sampled input signals of the signal path and the estimated filter coefficients, where the estimation is carried out so that a difference between the output signal and the estimated output signal is reduced. Each of the filter coefficients is extracted by a low-pass filter where the low-pass filter coefficient in the low-pass filter can be set to a constant. Normalization can be carried out in either the input side or the output side of the low- pass filter. Otherwise, the low-pass filter coefficient may be set to 1-K?Xj(m)2/r, where r is set equal to a norm of the sampled input signals in the beginning, and is then set to an integrated power of the sampled input signals.
