Title: Echo erasing device
Inventor: IGAI KAZUNORI
IPC: H04B3/23
Filed: 1986-07-14
Abstract: PURPOSE:To improve the converging speed and to obtain a long time of equalization by dividing with estimation an impulse answer of an echo path through an echo canceller of a small tap length and connecting the impulse answer to an echo canceller having a large tap length in response to increase of the cancelling value. CONSTITUTION:When the characterisitics of an echo path have a change and in a start mode, a control circuit 8 outputs the residual echoes of a 1st echo canceller EC1. Then the canceller EC1, the 2nd echo canceller EC2 and the 3rd echo canceller EC3 work independently of each other. When the residual echo output of the EC2 is smaller than that of the EC1, the circuit 8 selects the residual echo of the EC2 as an output and outputs the same correction coefficient to both cancellers EC1 and EC2. Thus the converging speed is improved and a long time of equalization is secured with an echo erasing device.
