PULSE DURATION CHANGER FOR STABLY GENERATING OUTPUT PULSE SIGNAL FROM HIGH-FREQUENCY INPUT PULSE SIGNAL AND METHOD USED THEREIN

摘要

The pulse width changes group to generate an input pulse signal (PLS10) longer than the pulse width of the output pulse signal (PLS11). Changing a pulse width group is, first, in synchronization with the input pulse signal input pulse signal than that produced this short first control pulse signal (CTL1) pulse width, and the first pulse width is longer in synchronization with the control pulse signals than the input pulse signal the 2 generates a control pulse signal (CTL2 / CTL3), by finally determined and hold the pulse width of the pre-pulse output signal (PLS13) as the pulse width of the second control pulse signal of the output signal when the input pulse signal having a very high frequency thereby maintaining a constant pulse width.
