Logic Gate Expressions

This computer science video follows on from the video about combining logic gates. It covers how a logic gate diagram can be described with a Boolean expression. This includes how to come up with a valid expression for a given combination of logic gates and, conversely, how to draw a logic gate diagram for a given expression. The order of precedence of the logical operations NOT, AND and OR, and the importance of brackets, are also discussed. It was the British born mathematician George Boole who in the mid 19th century, long before digital computers were even dreamt of, first described complex logical arguments using algebraic expressions that could be manipulated and simplified. Almost 70 years later, the American mathematician and electrical engineer Claude Shannon, showed that ‘Boolean algebra’ could be applied to the design of switching circuits; circuits that effectively handled binary ones and zeros. It was the work of these men that laid the foundations for the invention of the modern digital computer, and this video will give you some insight into how their work came together. This video also sets the scene for learning the rules of Boolean algebra, a very powerful tool for computer circuit design.

by far the most underrated CS-related youtube channel. this video was nothing short of a masterpiece. keep it up!

bless this video, simplified my EE class lecture in like 5 minutes!

[grayskies]

I am so enjoying this series of videos. I can't thank you enough for these! Sending love and thanks from South Africa

[eidechsearts]

Thank you so much! I was struggling on understanding how to draw the diagrams!

[epharathapalo]

U made it so simple and its really understandable. thank you sir

[primsiren]

Thank you so much. There is virtually no cs content on youtube for gcse, especially on vb, but feel much more confident knowing about this channel.

tbh.... I need to download all of your videos because I'm afraid if something will happen to such treasure.
I aid my self-study with your videos and it makes such a wonderful impact/experience, huge thank you!
I really feel like you love what you are doing, and that shows in a way how you explain things...
You are the third person on youtube that really knows what he is talking about, and I've seen so many.

bruv you explained in 6 mins what I couldn't understand for a week man tysm!

[russkiy_]

This is such a great video. I finally understand Logic Gates ! Many thanks !

[Mandroid]

This channel is so amazing thank you so much for this!

[lutherblissett]

Thank you for all the effort and knowledge.

[mckurlychek]

Thank you. This is the best explanation I've seen around.

[gfoddgr]

thankyou sooo much.. was strugling but now i understand soo well.. i dont think ill ever forget

[prathameshshinde]

this vid is so cool thank you made my computer science exam 10x times easier :) ty

[renamiyama]

thank you so much man this will help me in my topical test today. The video is so simple and easy to understand

[anthonybrown]

amazing explination... this is very complex for someone with my style of learning, and you managed to explain it better than my college teacher who lilkely took me for an idiot because he didnt realise i dont learn like other people

[aaronaustrie]

Hopefully, this tutorial will help me complete my HW assignment

[rudoend]

you made it so much easier for me!! thank you so much!!!

[TheeSlickShady_Dave_K]
