Abstract

PURPOSE:To obtain a correlation value approximate to human recognition, by weighting coincidence frequencies in all parts of the correlation between a digital input signal and a digital reference signal and weighting dissidence frequencies in parts where correlation is not important and adding them, respectively. CONSTITUTION:A digital input signal coming to a terminal 1 is supplied to a shift register 3 for 8-bit input signal and is supplied to exclusive OR circuits (EX-OR circuits) 14-1-14-8 from output terminals Q1-Q8 at the timing of clock pulses to a terminal 14. A digital reference signal coming to a terminal 6 is supplied to EX-OR circuits 14-1-14-8 from output terminals Q1-Q8 at the timing of clock pylses to a terminal 8. Mask data to a terminal 11 is supplied to a shift register 10 for 8-bit mask and is supplied to cathodes of diodes D1-D8 by clocks to a terminal 12.
