一、导线的屏蔽 1、概述当一个设备分成各自屏蔽的几个分机或若干个部件时,它们之间必须有导线或高频电缆连接,以避免导线辐射而造成对外界的干扰或从外界接收干扰噪声,从而形成部件分机工作不稳定。用于传输信号的传输线有双线传输线、同轴传输线及波导传输线等。 2、导线的几种耦合形式①导线间的电容性耦合由于两导线间存在着电容性耦合,导线与地间存在有噪声电压。如果不将两导线距
First, the conductor shielding 1, an overview When a device is divided into several extensions of their respective shield or several parts, they must be between the wire or high-frequency cable to avoid radiation caused by the wire to the outside world interference or receive from the outside world Interfere with the noise, thus forming an unstable working part extension. Transmission lines used to transmit signals are two-wire transmission lines, coaxial transmission lines and waveguide transmission lines. 2, a few forms of wire coupling ① capacitive coupling between the wires due to the existence of capacitive coupling between the two wires, there is a noise voltage between the wire and the ground. If you do not place the two leads apart
