我基本上想分解该图右侧的 ADC 块：
我希望将其分成 4 个部分。这意味着它所连接的每条线路都有一个部分。每个 ADC 块都有一个 I/O。
代码如下：

\usetikzlibrary{chains,fit,positioning}

也许可以直接在以下行中进行操作：
\node (adc1) [block] {ADC};
答案1
一个建议。我首先定义一种新样式block4，即rectangle split类型节点，即具有多个部分的矩形节点。shapes.multipart库因此加载。在adc节点中，将样式从 更改为block，block4并将节点标签更改为ADC\nodepart{two}ADC\nodepart{three}ADC\nodepart{four}ADC。

答案2
另一种解决方案。它保留phantomadc1 和 adc2 节点，因为它们稍后用于绘制连接。但是绘制连接时会添加一个单独的节点。
我也改变了内在foreach状态。
