Abstract

PURPOSE: To attain easy and high-precision positioning by an induction, etc., by obtaining a rectangular wave output of a period whose duty ratio varies with the phase of an output of a comparion between an output signal and a comparison signal of a specific period synchronizing with a reference signal.
CONSTITUTION: A comparison signal supplied from rectangular wave generator 33 to phase comparator 37 has a period one (n)-th [(n) is an integer more than two] as long as that of the output signal of sine-wave generator 34 and circuit 37 makes a phase comparison between this and the output of waveform shaping circuit 19 to output a rectangular wave of period nT whose duty ratio varies with a relative position between [(n-1)/2n] and [(N+1)/2n]. Integrator 53 integrates the output signal of terminal 51 of circuit 37 and that of terminal 52, its inversion signal, for a high-level period and outputs a difference between the both as a position detection signal from terminal 54. This signal has a duty ratio varying by one cycle by pitch- 1/n variation, so that positioning can be attained easily with precision (n) times as high as before.
