Abstract:
1. A system for determining a match between an unknown signal and a known signal, the system comprising: an input signal conditioner, the input signal conditioner comprising a receiver to receive an unknown signal, a detector to detect whether the unknown signal exceeds a threshold and to detect a sign of an integral of a derivative of the input signal, and a transmitter to output a conditioned signal, wherein the conditioned signal comprises a bit string; a memory to store at least one pattern to which the conditioned signal is to be compared to determine whether a match exists between the at least one pattern and the unknown signal, the at least one pattern comprises a bit string; a comparator, the comparator operatively coupled to the input signal conditioner and the memory, the comparator to receive the conditioned signal and the at least one pattern to compare on a bit by bit basis, the comparator outputting a count signal when the bit of the conditioned signal and the bit of the at least one pattern match; and an accumulator to increment on each count signal output from the comparator.
