I'm writing a blog and would like to include some circuit diagrams; it seems like they would be perfect for visualizing a process. Here's what I'm looking for:

- 2 Diagrams of different circuits that do exactly the same thing
- one circuit is simple, the other is unnecessarily complex
- perhaps some old circuit design from the 50s that was updated/simplified recently?
- I'm hoping there is some classic teaching example that is commonly used?

- It would be helpful if the contrast in complexity were visually obvious

The purpose of the comparison is to describe, in simple terms that anyone (including execs) should be able to easily understand, that 2 different processes can yield the same result but one of them is simpler and therefore easier to build, manage, produce, test, etc. while the other requires more components, and therefore costs more, is clearly less efficient, etc.

I thank the community for the help in advance. Happy holidays everyone!
