In the decoder designed for the DTMF Link project a Holtek HT9170B does the main job. The natural counterpart of the HT9200B used in the associated encoder (described elsewhere in this publication), ...

D156-tone multi-frequency (DTMF) Signals are used in touch-tone telephones as well as many other areas. The design method of the traditional DTMF signal encoding and decoding circuit is more complex ...
