Simulink® model of a dual-tone multi-frequency (DTMF) generator and receiver. Includes bandpass filter bank receiver, real-time soundcard audio, spectrogram of channel and uses Stateflow® block to store decoded digits.
NOTE: A version of this model which works with the current release of MATLAB® and Simulink is shipped with the Signal Processing Blockset™.
I did a DTMF receiver by eletronics devices, IC CM8870, and your idea taught a couple more about DTMF.
i like make control switch and delay with dtmf board thanks
it really helps me to understand the work of DTMF
Can i have the details of this experiment,in the code as well as block form in details as i am a postgraduate student of Victoria University of Technology, Melbourn ,Australia.
