The present invention relates to an echo canceling method and apparatus for simultaneously erasing echoes produced on a plurality of transmission paths. It is an object of the present invention to provide an echo canceling method and apparatus for multiplexed lines which require a short convergence time and a less amount of operations. As a means for solving the problem of the present invention, the echo canceling apparatus has a control circuit (70) which receives information on convergence degrees and input signal intensities from a plurality of adaptive filters (80, 81, 82) to distribute a number of coefficient updates to each adaptive filter corresponding to the information.
