These notes are the ultimate proof of an effective study guide: I used them to learn Digital Electronics from scratch in just three days, and scored 97/100 on the final exam.
When posted on Zhihu, these notes (along with my analog electronics summary) became a popular resource, earning over 5,000 likes and shares.
This is just one part of my HUST course notes collection. If you find this resource helpful, I'd appreciate a star on the GitHub repository!
