ABSTRACT:
A method of measuring echo path delay in a circuit having echo cancellers after enabling an echo signal to pass through the echo cancellers. The known time for a given echo canceller to disable is subtracted from the overall test signal duration. This quantity can be subtracted from the overall echo duration to compute the echo path delay.
