%X In this paper we explore the possibility ofusing time-frequency representations (namely theShort Time Fourier Transform) for the process ofdecoding Dual-tone Multi-Frequency (DTMF) signals.The paper shows the advantages of using timefrequencyrepresentation based detection in the case ofDTMF signals covered with noise due to impropertelecommunication channels.
