李沙育图形在电子测量中的应用浅析

On the Application of Lissajous Figure in Electronic Surveying

李沙育图形不仅能真实的反应了电子示波器测量的原理,还能测量交流信号的频率与相位.在该文中通过举例列出了如何快速的测量任意交流信号的频率与相位.

Lissajous figure can not only truly reflect electronic oscilloscope measurement principle, but also measure the frequency and phase ofac signal. By giving some examples, this article lists out how to rapidly measure the frequency and phase of any ac signal.
