Abstract(in English) | DTMF detector is the most important component of Voice Application Sever. This is implemented by using digital filter bank as a conventional hardware product. In VoIP the AS is implemented on a general purpose operating system such like PC-UNIX or WIN32. In these cases we show the advantage of Fast Fourie Transform (FFT) rather than filter bank for detection of DTMF. In addition to detection of frequency packet by packet. |
