Description
In this study, Dual Tone Multi Frequency (DTMF) signal generation and detection is implemented by using Goertzel Algorithm in MATLAB software. The DTMF signals are generated by using Cool Edit Pro Version 2.0 program for DTMF tone detection. The DTMF signal generation and detection algorithm are based on International Telecommunication Union (ITU) recommendations. Frequency deviation, twist, energy and time duration tests are performed on the DTMF signals. The algorithm recognizes the DTMF tones if they satisfy the recommendations, otherwise they are rejected.
