Abstract: PROBLEM TO BE SOLVED: To obtain a system having balanced responses of a direct channel and a delay channel by providing a continuous compensation low-pass filter in a 2nd channel to take balance of pulse responses of two channels. SOLUTION: This line is provided with a 1st channel which is provided with at least one continuous low-pass filter 20 performing smoothing and elimination of a clock residual and is sampled and a 2nd channel into which a continuous low-pass compensation filter 21 is inserted to take balance of pulse responses of the two channels and which is not sampled. Thus, the filter 21 is inserted into the direct channel to take balance of the responses of the direct channel and a delay channel. Consequently, it is possible to obtain a system taking balanced responses of the direct channel and the delay channel.
