Patent abstract
A communication device (e.g., a modem) is disclosed as including logic that processes a transmit signal before providing a signal to an echo canceler. The processing may include low pass filtering and decimation of the transmit signal. The low pass filter's cut-off frequency preferably is less than the sampling rate associated with the transmit signal.
