ABSTRACT:
An equalizing circuit comprises a hopping-type amplitude equalizer (70) for changing the characteristics of burst signals inputted sequentially thereto to desired characteristics. The output of the equalizer (70) is distributed by a distributor (23) to a desired number of paths. Each output path of the distributor (23) is provided with a hopping switch (25a, 25b, or 25c), which is operated in synchronism with the amplitude equalizer (70).
Consequently, even if the number of signal paths is increased, the number of equalizers required is smaller than the number of signal paths.
