ADD DTMF GENERATION AND DECODING TO DSP-UP DESIGNS (CONTAINS SCANNED TEXT)

Because of the programmability of the digital signal processor, the TMS32010 can also be programmed to handle Dual-Tone MultiFrequency (DTMF) encoding and decoding over telephone lines. For a system already performing digital signal processing functions using the TMS320, this DTMF capability may be obtained at no additional hardware cost. This report is a reprinted article from Electronic Design News. The article details the DTMF mplementation algorithm and provides TMS32010 program description and code.
