fsk to dtmf converter

Hi

This is a complicted project since you will need to decode DTMF (use 8870 to do that ) read it into a ucontroller and have the ucontroller generate Bel202 protocol data using the uart ,

Send the data to XR2206 FSK modulator and you got a sulation !


All the best

Bobi

Hi,

What are you trying to do? Whey covert DTMF to FSK? cant you use the DTMF and thats all?
Also have a look at this site:

They have lots of circuits for the Telephone and maybe one of them will give you an idea to overcome your problem.
Good luck.
