PURPOSE:to accurately detect the position by synchronizing and outputting the output signal of a trailing position sensor with that of a preceding position sensor. CONSTITUTION:When an encoder (not shown) generates an output signal A2, the value of a signal A2 of the falling time of a waveform shaping signal S1 is stored in a latch circuit LC1, and the value of a signal A2 of the rising time is stored in a latch circuit LC2. Comparators CO1, CO2 compare the outputs of latch circuits LC1, LC2 with the signal A2, and apply signals V1, V2 to an EOR circuit. The output of a flip-flop FF is inverted by the rise of the output EO of the EOR circuit to obtain a signal S2''. A selector SELEC switches input signals S1, S2'' by a select signal SS. |
