Abstract
Disclosed is a pulse detector that uses four samples of an analog signal to detect a pulse as soon as one sample beyond the time of the peak of the signal level at the pulse. The pulse detector can detect pulses by sampling at the center of a peak of the pulse or by sampling at either side of the peak of the pulse. The pulse detector detects pulses while tracking data, and it uses an alternate detection system for detecting pulses while acquiring timing and gain lock on a signal having a known data pattern. The detector uses either the sampled signal levels directly, or a moving average of two samples to perform the detection.
