Karnaugh Map Tutorial 4 Variable

[@maxzzz8191]

teacher taught this for like 5 straight classes and i had no idea what was going on and you managed to teach it in under 10 min... amazing

[@DigitalLogicAnalysis]

Thanks for the comment and the kind words ... glad you enjoyed the video! Cheers, Jim.

[@Grasshoppa065]

You, sir, are a fantastic teacher. I just spent 50 minutes in a lecture listening to a professor trying to teach this to a class and I just couldn't wrap my mind around it (not due to a lack of me trying). Then I watch this 8 minute video and I feel like I completely grasp the concept now. Thank you very much, you deserve my like.

[@azizanzakaria4185]

Thanks DigitalLogic . I'm 52 years old and I find your tutorial extreamly simple and useful.

[@MeditatingDennis]

God bless you. I was searching for an plausible explanation for over an hour now, until I came across this video.

[@daisylopezartist]

Thank God for online teachers like you! My professor in digital electronics teaches really fast and she has a really low voice.

[@mr_official_tech7734]

Daisy Lopez you are correct even my lecturer to.?

[@KusabeKuruyashiki]

Same

[@creativedestructions]

If I pass my exam this time around, it will be thanks to you....

[@OrnateOwl]

How did it go? :)

[@TofuCS]

how did it go

[@novattruldax1970]

how did it go?)

[@ambersummeralls4295]

Thank you for making it click! I could neither understand my professor's lecture nor any other K-Map tutorials.

[@Ava3267]

You're Awesome! Now I understand what I couldn't get in the class. Very simple and clear. Thank you soooooo much

[@arturfil]

I gotta say, excellent video after 6 years this is still explained perfectly! good stuff!

[@alexlarson4621]

My professor couldn't teach this as well as you have. No over complication. Thank you.

[@raz_xx]

i love this so much. i have computer architecture final on tuesday and this lecture is much appreciated.

[@ShreeVallabh29]

Ohh, really, 1st time i got such cool info about how to solve of k-map...my teacher always miss some part while teaching.. but these 8 mins are gonna save me from practical exams... TY mate! :D

[@venti42]

This is the best video ever for K-Map !!!!!!!

OMG, THANK YOU SO MUCH!!!! This is way 100x times easier to understand than my stupid textbook

[@roryridesabike]

Clear explanation, thanks buddy, helping an aspiring engineer!

[@DSt3f]

Thanks man, I just couldn't understand how the products formed from all the written material I've read. Now it's clear :D

[@DigitalLogicAnalysis]

Thank you for the kind words ... I'm glad you found it helpful.

[@DigitalLogicAnalysis]

Hi Asmaa, You're welcome! Glad you found it helpful. Cheers and thanks, Jim.

[@saras8970]

thank you very much! this video was one of the best videos I have seen on youtube! very efficient.

[@zendalski75]

confirm the same. excellent!

[@anuragtripathy9004]

you saved me from failing, thank you

[@DigitalLogicAnalysis]

You're welcome! Thanks for the comment and the kind words! Cheers, Jim.

[@DigitalLogicAnalysis]

Hi Ray, The values for Y are arbitrary in this example, but normally they would come from the truth table, which would come from the output of a particular circuit or design. The part I cover in this video, assumes that you already have the truth table outputs, and that you need to get a simplified Boolean expression. Hope that helps! Cheers, Jim.

[@DigitalLogicAnalysis]

Hi Khang, you're welcome ... glad you found it helpful! Cheers, Jim.

[@self-help-energy]

Thank you very much! It was really very helpful, as it was nicely explained. May God reward you for it.

[@neja2768]

It's so freaking hard to find any useful tutorials in this whole topic. (Digital Systems ) Thanks.

[@DigitalLogicAnalysis]

Hi Kyle, Thanks for taking the time to comment on the video. I often struggle with the speed to keep it moving at, since I don't want it to drag, but I do want to make sure that as many people as possible will find it useful, and not too fast an explanation. There is really a huge variety in people's prior knowledge, and learning speed, and I try and find the best fit as much as I can. Thanks for the feedback, and the compliment! Cheers, Jim.

[@DigitalLogicAnalysis]

Hi Daniel, Glad it made it easier ... and you're welcome! Cheers, Jim.

[@DigitalLogicAnalysis]

Thanks! I appreciate the feedback, and I'm glad you found it useful. I will be preparing some more videos soon ... if there is anything you'd like to see, please let me know!

[@ericm8849]

very easy to follow explanation, helped me a ton thanks a lot

[@DigitalLogicAnalysis]

You're welcome! I appreciate the feedback ... thanks!

[@DigitalLogicAnalysis]

Hey lovelybear29! You are very welcome! Happy you found it useful ... :) Thanks and regards, Jim.

[@cobyup10]

Cool approach. The way I'm being taught is with the variables written above and beside each column but this works well too. What was the original expression from which the values in the truth table came? Thanks!

[@DigitalLogicAnalysis]

Glad to hear it! Thanks for the feedback. Cheers, Jim.

[@DigitalLogicAnalysis]

Hi, Glad you found it helpful! Thanks for the feedback! Cheers, Jim.

[@malek6610]

From the bottom of mu heart .. thank you

[@ValyndiirTV]

Thank you for this, this made things clear.

[@georgegiannakakis2561]

Do you have any idea how the y result comes from sir?

[@DigitalLogicAnalysis]

You're welcome! Glad you enjoyed it.

[@xdinic]

Finally a good tutorial, thank you!

[@jurajzvarik4824]

thank you mate... you saved my life

[@DigitalLogicAnalysis]

Hi Manuel, Yes, it can be simplified to y=BC + !D(A+C). I would actually consider either to be fully simplified ... and just off the top of my head, I think either circuit would require five gates, but you are correct ... good eye! :) Cheers, Jim.

[@ronaldlimnyuy6039]

Perfectly understood thank you sir 🙏

[@msd999444]

my school teaches it like this... cd\ab, 0 4 12 8 1 5 13 9 3 7 15 11 2 6 14 10 makes this a little harder for me to follow, but still helpful.

[@DigitalLogicAnalysis]

You're welcome! Cheers, Jim.

[@BennyIsip]

Thanks a lot! Finally understood these

[@DigitalLogicAnalysis]

You're welcome!

[@sharifsircar]

Where was this 2 weeks ago. Thank you!

[@TerrenceJoneskrews_]

Thanks man finally learned the topic

[@h2s1mple15]

2021 God bless me that I will make this on my the most final exams

[@sam_cs_49er]

very helpful...i liked how you explained it!

[@DigitalLogicAnalysis]

Hi, Thank you! Glad you liked it. Cheers, Jim.

[@DigitalLogicAnalysis]

Thank you! Glad you found it useful. Cheers, Jim.

[@DigitalLogicAnalysis]

Hey, thanks for the comment and the feedback! Cheers, Jim.

[@DigitalLogicAnalysis]

Well ... there's usually more than one way to get things done when you're dealing with Boolean simplification. Still I hope you found this helpful in some way.

[@DigitalLogicAnalysis]

Thanks for the feedback! Cheers, Jim.

[@DigitalLogicAnalysis]

You're welcome! Glad it helped! Cheers, Jim.

[@DigitalLogicAnalysis]

You're welcome. Glad it was useful! Cheers, Jim.

[@DigitalLogicAnalysis]

Hi, You're welcome! Glad it helped. Cheers, Jim.

[@DigitalLogicAnalysis]

Thank you, and thanks for the comment.

[@ayacreame]

Thanks for posting this video. I can now understand it clearly. :D

[@corvoattano4544]

Thanks for the explanation.

[@ianos123]

Thank you soo much! But I have a question. How do I know if it is a conjunctions or disjunctions at the end for Y? And also, does everytime a proposition variable is only 0 - i have to negate it? Thanks again!

[@ianos123]

Ops, sorry for the stupid question. Its a disjunction if we cover the 1's and it is a conjunction if we cover the 0's.

[@il2xbox]

Thanks man, I completely forgot that the amount of cells in my groups had to be powers of 2. I kept making groups of 3 and wondering why my stuff wasn't working, lol.

[@DigitalLogicAnalysis]

You're welcome!

[@DigitalLogicAnalysis]

Hi, Thanks for the feedback and comment! Basically, the values for Y in this example (and the 3-variable) come from the truth table. Where those values come from, is from the circuit being designed or analysed. The steps I cover in this video assume that you have already got the values you need from a particular circuit or design, and that you now need to simplify them. For this example, they're just values I picked to illustrate the example, Hope that helps! Cheers and thanks again, Jim.

[@kanfusheng1347]

very good tutorial! thank you very much :D I finally undersotod how to do the labeling after circlign the loops! 10000x WAY BETTER THAN MY PROF!

[@Lukomeyan]

I tried to learn this from a textbook and I just didn't get it. After watching your 3 and 4 term videos I'm finally getting it. Thanks! :) I do have something that I don't quite get though; about the overlapping and what is unique or not (7:03)

[@Duhne1]

Great tutorial, cheers!

[@kostas.thanos]

You helped me, a lot! Thank you!

[@h4xX4rN12]

Great tutorial!

[@parthgandhi9972]

Damn it was soo halping...thankss alot.. i got my confusion clear..

[@DigitalLogicAnalysis]

The 1s and 0s get mapped from the truth table. I go more into detail about that on the 3-variable Karnaugh Map tutorial, so check that out, but if you still have questions after watching that, please let me know. Cheers, Jim.

[@ussul6524]

Gerat video. Thx. Now you can do one how to simplify expression.

[@soosXD]

you saved my soul, Thank you

You're welcome ... thanks for the comment!

[@wesleytorrez5537]

Holy shit dude you’re freaking amazing.

[@BCMCHINNI]

I'm sorry, but could you direct me to the video that shows how to get the Y values for SOP and POS? Thanks!

[@edward3105]

Where did you get zeroes and ones on the truth table, on Y side?

[@proatgaimz]

great explanation!

[@Serpentus]

Thank you so much You're a lifesaver

[@DigitalLogicAnalysis]

No worries ... glad to help! Cheers ...

[@DigitalLogicAnalysis]

Hi, You're welcome! Cheers and thanks, Jim.

[@vaggelismanousakis6147]

Are there any requirements in order to put the variables in the particular way DC/BA, for example would it matter if you wrote AB/CD or AD/CA ?

[@vaggelismanousakis6147]

it outputs diffrence result, can anyone help ?

[@tahy59]

fire explanation thnx sir
