ABSTRACT:
An extended length digital correlator threshold circuit for (N.multidot.Mit correlation using N M-bit correlators is disclosed. For the exemplary case where N=2, the digital correlator threshold circuit comprises: a first circuit for storing a preselected code word having first and second digital code portions; a first correlator responsive to the first digital code portion and an input digital data stream passing therethrough for periodically producing a first multibit number representative of the number of bit agreements between the bits in the digital data stream and the bits in the first digital code portion; a second correlator responsive to the second digital code portion and the digital data stream passing therethrough from the first correlator for periodically producing a second multibit number representative of the number of bit agreements between the bits in the digital data stream from the first correlator and the bits in the second digital code portion; and a second circuit responsive to said first and second multibit numbers for generating an output signal when the combined number of bit agreements in both of the first and second multibit numbers is at least equal to a preselected threshold number.
