摘要:
A peak hold circuit 11 holds a peak value of an output signal from a rotating angle sensor 6. A bottom hold circuit 12 holds a bottom value of the output signal from the rotating angle sensor 6. A threshold value is set from the peak value by the peak hold circuit 11 and the bottom value by the bottom hold circuit 12 by resistors 24 to 27, analog switches 28 and 29 and a NOT circuit 31. A comparator 10 compares the output signal of the rotating angle sensor 6 with the set value thus set, and outputs a binary signal (digitized signal) in accordance with the comparison result.
