DTMF_coding_with_TI
DL : 0
This application note describes the implementation of a dual tone multiple frequency (DTMF)tone generator and detector for the TMS320C54x . 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.

检测8K采样频率,16位PCM码流的DTMF信号 标准的DTMF双频的检测还是可以的 误差检测可能不是很精确......以后再优化 压缩包里有C源码,build出来的elf文件,原始PCM码流(Detect 8K sampling frequency, 16 bit PCM bitstream DTMF signal Standard DTMF dual frequency detection is fine Error detection may not be accurate... Compressed packets have C source code, the ELF file, the original PCM stream package)
