<p>/4,195 An integrator integrates the central portion of each signaling interval of a PCM input signal for a time less than the reciprocal of the PCM baud rate. Means responsive to the integrated signal or a manifestation thereof performs a comparison operation at the end of the integration period and stores the result until the end of the next following period. The integrator is reset between integration periods when transitions of the signal are likely to occur whereby immunity to PCM. signal amplitude variations and transition edge distortion is enhanced and the probability that the integration will be monotonic is enhanced, thereby reducing the detector error rate.</p> |
