Abstract

In this paper, a new algorithm is proposed for the DTMF detection. The modified DFT algorithm is employed to detect the band-pass DTMF signal. The computation requirement is very low than the well-known Goertzel algorithm. Moreover, the detection-criterion and correctionrate is still same as DFT and Goertzel algorithm. Experimental results confirm the good performance of this new algorithm.
