Abstract(in English)	In this paper, a review is given about the author's studies on adaptive filters in feedback systems. First, the results for the feedback-type active noise control are given by using the frequency domain technique. Next, as for hearing aids the scheme using two adaptive filters to identify the feedback path is explained when the input signal is modeled as an autoregressive (AR) process or a sum of sinusoids and white noise. The stability of this adaptive filter system. It is shown by the linearization at the desired stationary point. Also, a related topic is mentioned for transmission and reception with single frequency in wireless relay stations.
