... minimized. The design of an adaptive echo canceler involves many considerations, such as the speed of adaptation, the effect of near-end and far-end signals, the impact of signal levels and spectra, ... Because of the existence of the four- wire circuit between the location of the echo canceler and the hybrid, the impulse response of echo path is delayed. Therefore the initi...
