PURPOSE:To obtain a differentiating signal of an input signal including noise components, by providing an AND gate inputting both outputs of a D flip-flop and an RS flip-flop to an input signal. CONSTITUTION:The input signal (a) is given to the D flip-flop 4 together with a synchronizing signal (b). A wave-shaped signal (c) is inputted to an NAND gate 5. The NAND gate 5 and an NAND gate 6 form an RS flip-flop 10 and the 2nd synchronizing signal (d) in the opposite polarity from the signal (b) is given to the NAND gate 6. The output of the NAND gate 5 and the flip-flop 4 is inputted to an AND gate 7 to obtain a differentiation waveform (f) of the input signal (a). Thus, the differentiation signal is obtained with simple constitution. |
