I just came across your channel yesterday, watched most of your videos, and visited your website since then. This is an excellent learning material for beginners. I understand the effort you must put into making this worthwhile, and I want to thank you for that. Keep up this amazing work. Looking forward to your next lecture.

Thanks so much for sharing this. I love that the lecture provides both, some sound theory and also the dives into actual implementation problems encountered in practice. Keep on that awesome work.

Just a quick Q: With regards to the divider, could you use a couple of inverter gates to add delay to the feedback around the D-type FF, or would that be too much?

Just curious, What academic degrees do you have to post these lectures please ?!....
