应用中断控制技术测量不同频率方波信号的脉冲宽度。
The pulse width measuring of the different frequency square wave signals was done by using interrupt control technology.
它不仅可以测量正弦波、方波、三角波、尖脉冲信号和其他具有周期特性的信号的频率，而且还可以测量它们的周期。
It can measure not only the sine wave, square wave, triangle wave, a sharp pulse but also can measure other characteristics of the signal wave.
