ABSTRACT:
An impulse response of a litter may change in the output of a filter unit immediately after the generation of a litter according to a sampling timing signal from a timing regenerating unit if a filter unit is provided between an A/D converting unit and an echo canceler. In this case, a selecting unit in a jitter compensating unit compensates an uncanceled echo through each of the outputs sequentially selected by a plurality of adaptive filter unit. Plural sets of tap coefficients are stored in a tap coefficient storage unit, from which the selecting unit sequentially reads them to operate one adaptive filter unit, thereby reducing the size of a jitter compensating circuit.
