PURPOSE:To obtain many-divided signals through less detection parts by detecting 120 deg. out-of-phase signals, synthesizing those two signals and thus generating three 120 deg. out-of-phase signals, and dividing one period into six on the basis of those three generated signals. CONSTITUTION:Detection signals A and B having a 120 deg. phase difference are added together at a section 1 and then waveform shaping 4 is performed. The detection signals A and B are also waveform-shaped at parts 2 and 3 to generate mutually 120 deg. out-of-phase rectangular wave signals D, E, and F. When those signals D, E, and F rise and fall, pulse signals G, H, and I are generated and ORed at a part 8, thus obtaining a signal K generated by dividing the detection signal A or B into six. |
