Unlike all other posted DTMF programs, my application is specifically designed to simulate the working of a real DSP processor especially for beginners.
That would mean that digital oscillator was used to create sine and cosine functions and signal is passed through 8 filters. The signal is analyzed frame by frame and mostly likely digit is extracted based on repeating pattern just like a real DSP processor. Parameters like noise generation, signal duration, frame length are all adjustable to check at what noise levels the output will become irrelevant.

Please note that this is a single digit DTMF only. Also use help function to see all the equations used to filter the signal.
