Published Date: 10/01/1994


This voice-echo canceler implementation is based on a similar implementation using the TMS320C2x 16-bit fixed-point digital signal processor (DSP). This document shows the differences between the two applications and highlights specific TMS320C5x features that support a voice echo canceler. The appendix provides a schematic for a dual-telephone interface for the TMS320C51.
