DTMF Decoder

Question: How do I implement DTMF Decoder in PSoC1 ? I can't find the DTMF Decoder User Module available in PSoC1.



There is no DTFM decoder user module available in PSoC.  There are a couple of application notes that show how to implement a DTMF decoder in PSoC.  The application notes are:

AN2247 - Low CPU Consumption DTMF Detector

AN2122 - Standard DTMF Decoder
