PURPOSE:To always obtain a pulse of a fixed width having a certain interval of its preceding and next pulses although the pulse width or the interval to the preceding and next pulses have a change in a pulse shaping circuit that is used for a data processor and the like. CONSTITUTION:The 2nd FF6 is set by the output of the 1st FF4 which stores the input pulses, and the delay circuit 7 is driven by the output of the FF6 to produce an output after a certain time. The setting of the FF6 is suppressed while the output is produced at the circuit 7. At the same time, the 3rd FF12 is set by the output of the circuit 7, and this output gives an end to the procedure carried out with an input of the input pulse. Then the output signal is produced for a time during which the FF6 is set and the output of the circuit 7 emerges. And the output signal is suppressed while the output of the circuit 7 is produced. |
