DTMF generation and Comparison between FFT and Goertzel algorithms simulation based on GUI interface of Matlab

摘要：

This paper gives the principle of generation of DTMF signal based on the standard of ITU Q.23. Using the GUI interface method of matlab. we implement the simulation of signal generation. Then with the help of FFT algorithm and Geortzel algorithm, we complete the reception of DTMF signal and achieve the feature of frequency domain about the signal. By comparing these two methods, we get the conclusion that Geortzel shows a better performance than FFT algorithm in terms of reception of DTMf.
