Abstract
PURPOSE: To decide a signal accurately even if it is a fine pulse by inputting the fine pulse to a pulse width expansion circuit therefor.
CONSTITUTION: It is usually known beforehand that a signal A to decide is a normal pulse or a fine pulse hard to decide, and a control signal B relating thereto is inptted to gates 5, 7. In the case of normal pulse, the signal A to decide is inputted straight to a comparison circuit 9, where it is collated with an expected value signal D. Then in the case of fine pulse, the signal A is inputted to a pulse width expansion circuit 8, where it is expanded for decision, and then inputted to the comparison circuit 9.
