Abstract

PURPOSE: To properly detect the level change by effecting the comparison of the sample-held value before and after the level change takes place in the signals to be detected during integration.
CONSTITUTION: The signals to be fed to an integrating circuit 1 stepwise change. A hold circuit 2 generates signals 2b in accordance with pulse signals 2a. A hold circuit 3 generates signals 3b in accordance with pulse signals 3a. A hold circuit 5 generates signals 5b in accordance with pulse signals 5b. An arithmetic circuit 4 compares the outputs 2b and 5b of the hold circuits 2 and 5 thereby to generate output pulses 4a when the difference inbetween is higher than a preset level.
