Each encounters a reflective surface, the echo on the oscilloscopescreen 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.
