Description

This application note describes the implementation of a dual tone multiple frequency (DTMF) tone generator and detector for the TMS320C54?. This application note provides some theoretical background on the algorithms used for tone generation and detection. It documents the actual implementation in detail. Finally the code is benchmarked in terms of its speed and memory requirements.
