Echo cancellation system.

摘要

A circuit architecture suitable for use in a television receiver which effectively performs a ghost or echo cancellation procedure on post-echo components and pre-echo components occurring within the transmission channel. The apparatus features a filter circuit architecture which can be configured under programmed control so as to partition groups of its filter sections to form IIR filters and FIR filters. The filter architecture is suitable for use in multi-circuit configurations and can be used with clustering algorithms to increase the efficiency and optimize the use of the available circuit architecture.
