用V/F集成芯片实现谐振曲线的示波器显示

The Display of the Resonant Curve on Oscilloscope with V/F Integrated Slip

用普通示波器显示RLC电路谐振曲线通常是困难的。本文提出根据扫频测量的基本原理 ,用V/F芯片和锯齿波电路以及示波器的X轴外触发功能实现这种显示 ,此方法实现容易 ,显示操作简便。

In general, it is difficult to display the resona nt curve of RLC circuit by the oscilloscope. According to the basic principle of sweep\|frequency, this paper suggests that the display can be realized by the V/F integrated circuit, the saw\|teeth wave circuit and the x\|axis external trigger of oscilloscope. This method is more easy to realize and more simple to operate.
