ABSTRACT:
An echo cancellation circuit is disclosed for use with full-duplex data transmission systems. The echo canceller can operate in spite of time invariant non-linearities in the echo channel or in the implementation of the echo canceller itself (such as in D/A converters). The echo canceller receives an echo signal having linear and non-linear components and includes N linear tap weights for cancelling the non-linear components of that echo signal where M is greater than N but less than 2.sup.N.
