ABSTRACT:
This invention concerns an analog-to-digital correlator with programmable coefficients with values of +1, -1 or 0.
This correlator comprises a charge-transfer shift register to receive samples of the analog input signal for correlation, and two programmable digital-output shift registers, followed by memories to establish coefficients with values of +1, -1 or 0. Depending on the signal available at the digital register outputs:
