| Abstract: | A design and implementation of high density DTMF signal coder/decoder is describes in this paper The high- performance DSP and DTMF signal decoding algorithm are used in implementation of DTMF decoder while ROM stored DTMF signal wave is used in implementation of DTMF coder. This design scheme realizes a high-density 512 coders/decoders in a single board. The product has passed telecom test organized by Ministry of Information Industry and has been widely used in practice. |
