Logic Simplification Examples Using Boolean Rules 

this guy's voice is too sensual for math. he needs to start making audio books. like 50 shades of grey or something

Wish you were my digital electronics lecturer, lecturers shall follow the same teaching standards you apply, THANKS A LOT

Jake, Juan, omnia, Thanks for the kind words. Wanted to let you know I'm developing my own independent RU-vid channel. I've got a sample pack of lectures up right now. This channel is undergoing major development summer 2014 but periodic updates will occur between now and then. Subscribe to it if you're interesting in the updates. Long terms plans include a complete basic electronics series (DC, AC, 3 phase AC), control electronics, power electronics, hydraulics, renewable energy, and more! The website will redirect to the RU-vid channel for phase 1 of development. Enjoy!

This video helped a lot. Thanks for posting this! I should ace my test tomorrow for sure..

Are you allowed to go F = A´ (B´C´ + BC) → F = A´(1) ?? Since A + A´ = 1

Wow! This method is save lot of time! Thanks

for 3rd example i got X= AC+BC+B'C'.. Is that correct?

This helped me a lot.

super helpful - thank you!

you are a Hero!

well that was really useful !

So the "Wizard" pictured in this video is not Jim Pytel? I don't believe the answer to question number 4 at the end of this video is correct.

nice

lol, 100 push ups as penance you say.

-A'BC'D + AB'C'D + AB'CD' + A'BCD' = Y If anyone could pls simplify this will save my life...

LIKED

You are organized.... And a wizard.

Thank god you made this! I swear there are teachers teaching boolean logic who do not understand or can explain what they are doing? Or simply miss step expecting everyone understands what they have done.

Whoever you are, fucking thank you !

You were more helpful than my teacher

Mr. Pytel!! You do such a great job with these videos. You teaching style is clear and effective. This video in particular practically saved my semester!! Thank you so much Jake

I don't smoke sir. By the way, this is honestly the best video around for Boolean algebra!

Very well done. Best explanation of boolean simplification I have found on the interwebs.

Please correct me if I am wrong and a justification would be great. At 28:00 , can we simplify the B'C' + BC to just 1 therefore getting just AB'?

legend, "If you can't explain it simply, you don't understand it well enough." and you sir know it more than well

Great Stuff Man . It's very helpful and appreciated . Got all last test right .So Happy . Really good work sharing , effective lessons

Exercise 3, the expression is as follows: (NOT A && NOT B && C ) || (NOT A && B &&C ) || ( A && NOT B && NOT C ) || ( A && NOT B &&C ) ||( A && B &&C ) The result professor Pytel got is: (A && NOT B) || ( NOT B && NOT C) || (B && C), which might be wrong. Checking the expression with WolframAlpha the result is: (A && NOT B ) || C Am I missing something here, or is the video solution wrong? Aside from that I would like to issue a big "THANK YOU" to Columbia George Community College and Jim Pytel for excellent lessons.

great presentation and had me chuckling throughout (saying i don't care in a very passive fashion gets funny after a while). You should make a video on logical equivalences, it would really help a fellow computer science major out.

at 20.17 could you rearrange the expression so you group the first and third term together and as a result get A B' C as your answer???

in expression number 7 how did he get "BD"? or did i mess up on writing the expression... i thought it was BCD instead of B(D+E) and that parenthesis after the E was a typo :c other than that i got all of them right on my exam :D

in ex3,i have different answers in diffrnt solutions

You're awesome, I wouldn't be getting through my digital systems class without these videos

"Are you a wizard" was pretty accurate, sir! :) Thanks for the lesson.

Question number 7 at the end is a little confusing based on the extra parenthesis after the E term. Other than that, great video, extremely helpful!

Thank you so so so much. You're a great lecturer

this video helped me SO SO SO much. THANK YOU Sir!!!

really love this guy. His voice reminds me of Ira Glass

Thanks very much indeed for explaining clearly

I got this problem: not(a) not(b) not(c) not(d) + not(a) not(b) c d + a b not(c) not(d) What is the simplest answer for that? because I got not(c) not(d) + not(a) not(b) But the answer is not(c) not(d) + not(b) c

Thank you Very much Mr.Jim Pytel.This helped me lot

Number 11 A+A'B = A+B ? Can you prove it or simplify the equation. I am confused

Thank youu Jim, veryy well explained !!

You explained this so much better then my prof. She cant explain how to do this and we have a test in 3 days on this.

thanks...but i think that the ans of ex7 is wrong and the right ans is B(D+E) ggggggggg

Great Work !! :D

very nice its awesome You understand me the whole....very thankfull 2 u god bless u

sir, how did you get # 2 and #4 :(

It came to me. Might logic simplification rules apply to web application? Im more into programming at the time. If i'v just made a complete and complex web page with cms (in object oriented code in PHP), and then written it out in this logic scheme manner. Then could i simplify application patterns?

I love this guy!!! I knew this stuff can be fun, unlike my professor.

Thanks allot. These videos have helped allot with my Grade 12 et mid year

Thank god for this step by step video 😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀😀

11:41 ;)

Much better than my teacher

You are a legend!!

Thank you Mr Pytel your videos help soo much!!!

It helps me a lot. Thank you so much for the clear and detailed explanation. I am new to this subject after I saw your video, I feel so comfortable. Could you please provide more videos with the different examples?

LOL, who in the heck downvotes a video like this?

can I write C+(AB) as CA+B using associative law. plz sir answer this question

How can A + ~AB = A + B? How do you get to that point?

Great video, thank you!!! I didn't know a lot of those rules, now it's much clearer!

in EX3 i solved another terms together leading to this solution AB'C using the first and third term together and the second and fifth term together so does this mean by taking another way of simplifying the result may change?

expression 7 gave me BD+E+D'F

In your number 11 law, isn't A+A'B = A XOR B???

how to simplyfy the boolean expression

OMG that's so helpful !!!thank you so much!!!!!!!!!!

Thank you so much for this video 😍

a wonderful explaining

Can you prove A" = A ?

Thank You for this video it really helps ! :)

Can't thank you enough, May God bless you.

wow, your awesome :)

you are great Sir .....

thank you sir

u save me thx

good

ak number ..

:)

1. simplify the Boolean expression using Boolean algebra:- a) AB+AC+BC=AB+AC B) (A'+BC)' (A'B'+ABC) 2. State De-morgans law prove the following using Boolean algebra theorem:- AB+AC+BC=AB+AC
