The conventional methods to detect the DTMF signals are accomplished by comparing the power of an input signal using the DFT. This paper proposes a new DTMF signals detector using a multiplier-less resonators which have not the multiplications to get output signals. The proposed method detects the DTMF signals using whether the outputs of the multiplier-less resonators resonate or not. This processing is realized by controlling a downsampling ratio, that is, a time component of the input signal. Therefore, the simple algorithm which can mainly be processed by the additions and subtractions is derived. We compare the proposed method for the DTMF signals detector with the conventional method in terms of the computational complexity and show the detection performance of the proposed method.
