Abstract
A new single-chip echo canceller has been developed. In addition to offering improved performance over an earlier single-chip echo canceller [14], the new canceller has many desirable features not available before. The most important of these features is that multiples of the chip can be connected in cascade to synthesize very long impulse responses. This paper describes the new features implemented on the chip and characterizes its performance.
