1. A signal detector circuit comprising:

  • a. a peak detector that receives as input spectral information for successive time intervals of activity in a frequency band, detects one or more peaks in the spectral information and outputs information identifying peaks for each time interval; and

    b. a plurality of pulse detectors each coupled to receive as input the output of the peak detector, wherein each pulse detector detects signal pulses that satisfy one or more characteristics based on the output of the peak detector.
