本文介绍一个简单而又经济的触发线路,这个线路已成功地使用好几年了。该线路可以产生一个上升和下降时间小于10毫微秒,脉宽从15毫微秒到大于1微秒的脉冲。仅仅改变一个电容的数值,就可以获得这个变化范围且不影响输出脉冲的上升和下降时
This article describes a simple and economical triggering circuit that has been used successfully for years. The line can generate a pulse with rise and fall times of less than 10 ns and pulse widths of 15 ns to more than 1 μs. Just change the value of a capacitor, you can get this range of changes and does not affect the output pulse rise and fall
