Abstract

In order to establish rapid diagnosis in the TDX signaling service, this study has analyzed the signal spectrum of the PCM acquisition system. The system has the function of acquiring the PCM signal of the preferred channel from the subhighway (SHW), connecting a universal signal transceiver unit and time switch unit, and then classifying the type of signal such as R2MFC/DTMF/CCT/voice, and finally discriminating the digit. This paper describes the spectral analysis of the PCM acquisition system using the quick Fourier transform (QFT), and discusses the signal analysis and discrimination algorithm
