带有 circuitikz 的传输线

使用彩色矩形（条带）绘制传输线更加方便，如下图电路所示

在此处输入图片描述

而不是使用标准circuitikz符号 在此处输入图片描述。

我对 TeX 的了解不够，无法做到这一点，但是您能否提供解决方案，让一个人可以控制传输线的矩形符号的长度，或者灰色矩形的行为类似于电阻器的端口？

答案1

一个简单的选项；），绘制传输线是使用库decorations.markings，在我的示例的情况下，声明了 3 个标记，一个声明起始坐标，一个包含标签，一个包含最终坐标并绘制一个矩形，如示例所示，以下是 circuitikz 中的代码，留下空格然后绘制每条传输线，因为对于我的解决方案，我无法将它与包的电路语法集成。

结果： 在此处输入图片描述
