说明： Goertzel算法是DTMF信号检测的核心,它利用二极点的IIR滤波器计算离散傅立叶变换值,快速有效的提取输入信号的频谱
(Goertzel algorithm is the core of DTMF signal detection. It uses the two-pole IIR filter to calculate the discrete Fourier transform value, and extracts the spectrum of input signal quickly and effectively.)

This DTMF generator and detector using Goertzels algorithm is developed mainly for educational purpose only and not for commercial usage.
Incase if you are a fresher to MATLAB: Open MATLAB and run the file "GUI"

I have made it a point to consider all aspects of a DTMF generator and detector while developing this software,If anybody has any additions,ideas about improvement,comments,suggestions or any kind of criticism is always welcome.You can email me on
Email: pranamjanney@yahoo.com.
Files:
Cal_k.m
decoder.m
generator.m
stringnum.m
goertzel_algo.m
gui.m
gui.fig
The GUI has opions to select Number of samples and noise power.I have also included sound for the output signal!
Please feel free to email me!....
