Abstract :
The authors have developed a PCM signal acquisition (PCMA) system in TDX-families signaling service equipment. They develop the quick Fourier transform (QFT) for length 2M data to analyze the power spectrum of the PCMA System. This algorithm can reduce the number of floating-point operations necessary to compute the DFT by a factor of two or four over direct methods or Goertzel´s method for prime lengths. In the experimental results, the system classifies the type of signals and finally discriminates the digits
