伟大领袖毛主席教导我们:“打破洋框框,走自己工业发展道路。”本文介绍一种测量晶体管或数字电路的简易方法。这种方法不用宽带示波器,也不用采样技术,仅用几种简单电路就从电表上直接读出晶体管或数字电路的开关时间。这种方法虽有看不见波形的缺点,但由于其结构简单,使用方便,最终结果又转变成直流电压,所以适合于大量检验和分类,也可作为开关时标自动分类的检测电路。 Great Leader Chairman Mao teaches us: “Breaking the Box and Taking Your Own Industrial Roadmap.” This article presents a simple way to measure transistors or digital circuits. This method does not use a wideband oscilloscope, nor the sampling technique, only a few simple circuits from the meter directly read out the transistor or digital circuit switching time. Although this method can not see the shortcomings of the waveform, but because of its simple structure, easy to use, the final result into DC voltage, it is suitable for a large number of test and classification, but also can be used as a switch automatically detect the classification of timing circuit.
