Each encounters a reflective surface, the echo on the oscilloscope screen displayed the impedance difference between the two interfaces also determine the level of echo amplitude.
每遇到一个反射面时，回声在示波器的屏幕上显示出来，而两个界面的阻抗差值也决定了回声的振幅的高低。
An oscilloscope is a test instrument that displays electronic signals (waves and pulses) on a screen.
示波器是一种在屏幕上显示电信号(波形和脉冲)的测量一起。
Therefore, the curve of voltage transmission characteristics of both TTL inverter and CMOSinverter can be displayed on the screen of an oscilloscope intuitively.
从而使TTL反相器和CMOS反相器的电压传输特性曲线能够在示波器荧光屏上形象而又直观地显示出来。
