Abstract

PURPOSE: To enable the detection of a rotational frequency with a detection sensitivity twice as high as input signals and the detection of a revolving direction by using two signals of different phases which are proportional to the rotations.
CONSTITUTION: To input terminals 6 and 7, two pulse signals which are detected by a non-contact sensor, respond to the rotation of a rotating object and have different phases from each other are inputted, and these two pulse signals and inverted (11, 12) pulse signals are applied to the terminals of flip-flops 13W16. To an output terminal 8, the doubled signals of the signals inputted to the terminal 6 are outputted regardless of the revolving direction of the rotating object, and to an output terminal 9, an H level is outputted for normal revolution and an L level for reverse revolution.
