Abstract: PURPOSE:To efficiently detect correlation by using a traditional SAW matched filter even for a diffused code with a long cycle by providing first and second surface elastic wave(SAW) matched filters and a delay circuit. CONSTITUTION:A signal to be inputted to the second SAW matched filter 23 is inputted after being delayed by the delay circuit 22 later than the signal to be inputted to a first SAW matched filter 21 by time equal to the delay time of the filter 21.
