Abstract

This appendix describes the implementation of an efficient filter structure for use in 8 Khz-16Khz interpolators and decimators which may be used in sample rate converters for audio conversion in emerging video telephony or audio sub-system applications. Specifically, this system was designed to provide conversion between G.71 l/G.728 and G.722 (narrowband to wideband audio) within H.320 for use in the QomsrM program.
