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 2^M 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
