Abstract

PURPOSE: To make it possible to remove a signal other than one having a prescribed width without altering the pulse width of a signal, by setting the relation of a prescribed pulse width and two long and short delay times to a required one and combining three signals to take the logical product conjunction thereof.
CONSTITUTION: A discrimination signal S1 is inputted to a delay line 4 wherein a delay time is Td1 and the delay time of an intermediate output terminal is Td2. When the pulse width Tw of an input signal is Tw<Td1-Td2, the two input terminals 6, 7 of NAND2 are not simultaneously brought to "H" and, when Tw>Td1, the two input terminals 5, 6 of NAND1 simultaneously come to "H" and, because the Q1 output terminal of FF1 comes to "L", no signal appears in a final output terminal 9. When a signal having a normal pulse width Tws is inputted and Td2>Tws>Td1-Td2 is formed, FF1 is not brought to a set state while FF2 is set and, therefore, an L-level pulse is generated in the output of NAND3 and a pulse having a pulse width same to that of an input pulse and a delay time of Td2 is outputted from an inverter INV.
