I can’t imagine I am without this video by going through my course. Bro, great job

[@NERDfirst]

Hello and thank you very much for your comment! Glad to be of help =)

Brilliant and Excellent video. Explanations, diagrams and plenty of relevant examples. This is the ideal video to learn about K-maps. Hats off!!!

[@NERDfirst]

Hello and thank you very much for your comment! Very happy to be of help =)

[@rathermousie]

Very helpful. This was much easier to understand than my professor's explanation.

People like you saves millions of lives each year.......

[@NERDfirst]

Hello and thank you for your comment! Millions might be a few too many, but I'll take the compliment! Glad you liked the video =)

[@hobbes2555]

Ok now this one is good. It explains the why behind the maps and why we select parts over others. All the other videos just rush through and give final results without explaining how they get there. Thank you.

[@NERDfirst]

Hello and thank you very much for your comment! Really glad you found the video useful! I think I went into this level of detail because I personally had a lot of trouble just... _getting_ Karnaugh maps in general. Glad to know that was a good choice =)

[@hobbes2555]

0612 TV w/ NERDfirst You're welcome. I'm a software engineer student, so anytime I need more info I'm going to search your videos first. I'll like and comment on the ones that help me out. Already subscribed! Cheers

Omg thanks for much. I was really confused on the variable portion but your color code in 15:06 was so helpful.

[@NERDfirst]

You're welcome! I struggled with these a fair bit as well when I first came across them, and that was what helped me at the time. Glad to be of help =)

[@nahiyanalamgir7614]

You covered everything in 20 mins what my instructor covered in 2 months.

[@NERDfirst]

Hello and thank you very much for your comment! Yeah I know what you mean. Sometimes in a school context there are just too many things to handle and the curriculum gets messy. Glad I could help out with that situation :)

[@nahiyanalamgir7614]

Yes. We're all grateful for your quality content. Thank you very much.

[@omaralhelo9442]

Best explanation ever ! I've just discovered your channel and can't wait to see all the other videos. By the way, can you make an explanation about Quine-McCluskey algorithm for Logic circuits

[@NERDfirst]

Hello and thank you very much for your comment! I haven't heard of the Quine-McCluskey algorithm before today, but I'll look into it and see what I can do!

[@warrengray610]

@@NERDfirst Thank you! I wonder have you produced a video covering the k map of a 7 segment display digit, I am trying to learn about the subject and it gets a bit overwhelming as the variables increase, I am certain I could learn from your good presentation method

[@NERDfirst]

Ooooh, that's an intriguing idea. Though at first glance there isn't very much to do - KMaps are useful for reducing things that are in the "sums-of-products" or "products-of-sums" format. For a single 7-segment display, it's really only a product (ie. an AND of all the segments that need to be switched on, AND the complements of the segments that need to be switched off) - there are no sums involved. eg. To get the number 5 (according to this diagram: en.wikipedia.org/wiki/Seven-segment_display#/media/File:7_Segment_Display_with_Labeled_Segments.svg), the expression is just: ACDFGB'E'dp' Since there are no sums ("ORs"), there's really nothing to simplify.

[@maazahmedpoke]

15:00 Wouldn't A'C +AB be the most simplest solution or am I missing something?

[@NERDfirst]

Hello and thank you for your comment! That wouldn't work as the input 000 would not give you an output of 1: A'C + AB = 1x0 + 0x0 = 0

[@maazahmedpoke]

​@@NERDfirst yes thank you. I was simplifying the statement using boolean algebra and missed a step. I'm just wondering what's the efficacy of using Boolean algebra to simplify instead of K-maps? which technique scales better?

[@NERDfirst]

Oh, Boolean algebra scales better for sure. I shudder at the thought of drawing K-maps for, say, 7 or 8 variables. And don't forget, the key advantage of a K-map is the ability to visually see relationships between the 1s (or the 0s) - Once you have a large map it becomes difficult anyway which defeats the purpose.

[@ApartmentAngelsFireStarters]

dude just summed up one of my computer engineering course

[@NERDfirst]

Hello and thank you for your comment! Does your course really only cover this? That's not really a lot for a full course. At any rate, hope this summary was useful for you!

[@ColeAlexanderSoftware]

So do keeping all of the groups as large as possible, even if not required to get the result, minimize the number of gates required further?

[@NERDfirst]

Yes, exactly! The idea is, since each group represents many of the possible outcomes AND can do so with a reduced number of gates, we aim to have as few groups as possible, that are also as large as possible. That's also why we're so happy to make use of the "don't care" conditions - Because they help us make larger groups!

[@divyeshrathod996]

in which software u desiign k map

[@NERDfirst]

Hello and thank you for your comment! The Karnaugh Map designs you see in the video were all created as part of my slides. Any slideshow application would do, eg. Powerpoint or Google Slides.

elisabet resbal do you use the kmap result to make the circuit or the truth table output?

why u talk to much on the next video directly on topic

[@NERDfirst]

Hello and thank you very much for your comment! I'm sorry you've had a bad experience! Unfortunately these videos are catered to those with no prior knowledge at all, so it's necessary to establish the fundamentals before we jump into the main topic!

[@abibossmeka7974]

@@NERDfirst i konw that but u go far beyond

[@NERDfirst]

Hello again! I understand your frustration but I'm afraid it's a necessary evil. After all, not everyone has as much background knowledge as you do :) As a general rule of thumb, for longer videos (and not just for mine!) check in the video description. As in this case, I've included timestamps for you to jump ahead!
