ABSTRACT:
An adaptive digital filter employs sequentially connected shift register stages to produce an N-fold correlation of pulses within a pulse train that satisfy search criteria. Once a signal has been acquired, a processor adaptively changes the tolerance length of the shift registers; the shifting clock and the number of stages to generate a real-time processed signal that tracks the source of the pulse train.
