Abstract :
Dual tone multi-frequency (DTMF) receiver based on modified Goertzel algorithm is developed. Performance of receiver is assessed under the ITU Q.24 standard specifications. The algorithm was tested with a variety of signals including speech, music, and DTMF tones. We found that this detector was efficient, reliable, and exceeded Bellcore standards
