Abstract
A pulse duration changer generates an output pulse signal longer in pulse duration than an input pulse signal, wherein the pulse duration changer firstly produces a first control pulse signal synchronous with the input pulse signal and shorter in pulse duration than the input pulse signal, thereafter, produces a second control pulse signal synchronous with the first control pulse signal and longer in pulse duration than the input pulse signal, and finally defines the pulse duration of a preliminary output pulse signal as long as the second control pulse signal, thereby keeping the pulse duration of the output signal constant when the input pulse signal has an ultra high frequency.
