Digital Logic - Karnaugh Maps

This is one of a series of videos where I cover concepts relating to digital electronics. In this video I talk about Karnaugh maps and how to use them to turn a truth table into a simplified logic expression.

[@raszelast]

Yeah, this is what I need! Short and to the point, thank you very much.

[@ParagonShepard]

Thank you! you are more methodical and helpful than my professor. I kind of get Karnaugh maps now. Hopefully enough to get through the FE exam.

[@Zak.f]

Thank you so much for taking the time to explain this concept!

[@vitotito12]

Thank you finally, got the logic behind the 4 variable map.Going to ace the test :D

[@soidus]

Sir, you are a genius! Hopefully I can rely on you to understand this subject instead of my instructor!

[@chrishadjipetris6059]

Karnaugh maps are helpful for up to 4 bits. This is the reason nowadays digital circuits industry uses hardware description languages to design their systems, such as vhdl and verilog

[@shabzb13]

Dude your amazing at explaining!!

[@jabbb1259]

thank you so much even the rubber sound kills me

[@chadcastagana9181]

2:34 I thought that Gray Code was just another name for Reflective Code ?

[@jahirulislammonir3490]

Nothing to say about you and your explanation.. Cool :)

[@bananalasmari7644]

thank you :)

[@SandunilJayasinghe]

Awesome! :)

[@twitchmix9415]

You are awesome!

[@DivjotSingh]

Amazing way for grey code generation !

[@umairameen1239]

Nice way of writing.

[@h14ksa]

great job .. thank you

[@mosestnjovana6124]

Hello Sir, thanks very much for the video. I am, however, getting different results in the 6 Variable K-Map with your method, in comparison with the method of drawing 4 different Maps. Please kindly assist.

[@ricrook3371]

can u tell me what's your principle filling up the 1 , i mean where do u fill 1 a and where do fill it 0 because it's impossible in the truth table by AND A,b,c,d,e,f, all must be high in order the output be high

[@Nuram0]

those are probably examples, because he has no real example of a circuit. If you have any circuit you should firstly try to fill out a truth table for better comprehension. If you have succesfully filled it out you can take the values of the table and insert them "graycode"-wise in the Karnaugh-diagram. Then choose wheather you have more 0's or 1's which one you want to combine together. If you have chosen one of them then go for the Disjunctive normal form (DNF) or the Conjunctive normal form (CNF). Then pass on as explained in the video. After you finished your "extraction" you will now have a short form of a logic expression. Sometimes you can use De Morgan or other rules to shorten the expressions even more :D

[@vorpalinferno9711]

Do N variable(N is extremely large) Karnaugh maps ever show up in practical applications? If so then what is the approach to analysis?

[@gruguntermench6097]

Andy Stix? Is that you?

[@JSbean]

At 13:44 how is c bar alone common and the column represents "CD" ? Where u have not b and not c, asking cause I'm not sure

[@dirasadirasa2499]

are u still want the answer ?

[@TheAdlcn]

gray code amazing !!!

[@gianlucadantonio7924]

ahaha ..informative and yet so entertaining

[@danielm3569]

Great Video! I am curious if you are trying to go for an Isaac Asimov look.

[@J1432]

Perhaps inspired by him but I don't have the guts to grow it out as big as him.

[@diegoquezada619]

gracias chupete suazo

[@PixelXephos9]

He looks like Tobey Maguire from spiderman XD
