  • Abstract
    A single chip, 128 coefficient, asynchronous echo canceller is presented. Cancellation is performed by an FIR filter whose coefficients are adapted using the power-of-two modified LMS algorithm. The pipelined circuit updates all coefficients and generates the filtered output every cycle while allowing a sampling rate >206.5 kHz
