READ THE FIRST TOPIC IN THE SERIES OR YOU WILL NOT UNDERSTAND THIS!
You know logic gates, but they are represented with different symbols. To read circuitry documentation and overall learn circuits, you need to know these symbols. They are not a priority to memorize, but they come in handy.
You may need light mode to see some of these images, sorry about that
If your system fonts are not up to date you might not be able to see some of the symbols.
