Boolean Algebra 3 – De Morgan’s Theorem

This video follows on from the one about simplifying complex Boolean expressions using the laws of Boolean algebra. In particular this video covers De Morgan’s theorem and how it can be applied, along with the other laws, to simplify complex Boolean expressions. It includes worked examples and some exercises you can try yourself, along with solutions.

So professionally done. This is what YouTube was made for.

Thank you. I am enjoying myself greatly working through these videos.

God bless this video series, it helps me to pass Computer Science class. Thanks for the info sharing, have a super day!

I am in a 5week accelerated program for Mechatronics Engineering. Part of Mechatronics is computer science. I am in a Digital Systems 1 class. This is about as hard as it has gotten so far, and I am a junior. Drinking through a waterfall is more like it than a firehose as Iwould normally say. I am definately thankful for these videos you have made. I would be 100% lost without them. Everything is so well explained and put together and clean and concise. My text book for this course is just hard to look at in general. Thank you for these videos. I will definately be revisting them time and time again, I will not be able to master this subject in 5 weeks the way I would like, but I am already scribbling these videos into my future schedule until I can pound these expressions down with quickness and confidence. Thnak you again Computer Science! You are awesome!

Wow, the execution of the series is just perfect

Many thanks for the video, excellent resource for use with A-level CS students

This channel deserves a million subs. The videos are very to the point and helpful. I've learnt a lot from these.

FINALLY some who explains each step of the solution! I couldn't find any video or tutorial about this in my first language. Each time the teacher jumped through the steps like it was all self explanatory, so eventually i started to think i was too just dumb to understand. With your videos i finally get it!! Thank you for giving me hope again ;), especially by saying it takes time to develope this skill!!

[mostafaaldgeir]

thank you a lot.I spend a whole day looking for a good explamention

At 11:48 you could remove the brackets which would result in (X V Y) ^ `X ^ Y. Using the absorptive law (X V Y) ^ Y = Y. So `X ^ Y

Thank you very much for these videos, you taught Boolean Algebra very well.

This video need more likes for his work.

Thank you so much for all these videos man! Definitely valuable resources for those who didn't really pay attention during class, lol.

[yawsokpor]

This is very important and one must understand

[tusharmahajan]

At 2:54 how can you just swap the OR for the AND? Wouldn't that change the meaning of the expression?

[hugofriberg]

I find: ¬(A ∧ B) = ¬a ∨ ¬b
really similar to: -(a + b) = -a - b
Since both expressions switch the middle operator, and negates the values of A and B.
