DTMF Encoder/Decoder GUI





  • Background: Touch Tone Dialing, invented by AT&T makes use of two signaling tones to indicate the numbers dialed by users in the system.  This system is called dual tone multifrequency (DTMF).
  • Obviously, to determine the numbers that have been dialed requires determining which frequencies are present.  The heart of a decoding system for DTMF is filtering.
  • Description: A phone-like DTMF tool with GUI using several methods, FFT, Goertzel and filter banks. This software implementation is designed on MATLAB environment.
  • Objective: to create a digital DTMF encoder and decoder in MATLAB.
  • Environment : MATLAB
