Abstract

PURPOSE:To discriminate the width of an input signal with a simple constitution, by applying the input signal to the D terminal of a D flip-flop (D-FF) and a monostable circuit and applying the output of the monostable circuit to the trigger terminal of the D-FF. CONSTITUTION:At the rise of an input signal in a terminal 1, a monostable circuit 2 is triggered, and an output inversion Q is low-level for a constant time. Since a D-FF 3 is triggered at the fall of the output of the monostable circuit 2, the D-FF 3 outputs a high level if the input signal is high-level at this time. Othersise, if the input signal falls already, the D-FF 3 outputs a low level still.
