Thank you so much for your help Mr. Neso Academy. You've helped me pass my CS courses. After this pandemic, I hope to see you in person and shake your hand. TY bro
for me u'r the best teacher on youtube u deserve to be the first one on TH-cam and more !!!! all ur videos are clear helpful and u give chances for students to go inside the amazing world of electronics 😊😊 🔝🔝🔝
Thank you so much Neso academy for explaining Each and every concept of digital electronics in such a brilliant way. All the lectures are really helpful for me.Thanks again😊
Hello Sir, Thanks for the great tutorial. I was wondering what practical application does the don't care condition serve, also how do we implement this condition in a real life scenario?
The only difference within the 2 truth tables is m6 and m7, and as specified, you don't care if the answer of m6 and m7 is 0 or 1. so the expression can be simplified.
I m new to this subject. i don't know your name. but dear sir. you r awesome. i thought this topic is very complicated . but u made this thing as clear as water. thanks a lot. i appreciate your presentation ... thns thnks thnks a lot. in the morning i m going to attnd my final xm and i was worry about this topic. thnks a lot sir..
In the final step, you arrived at F=A+B, right? Then you said that that was the same as F=A'B+AB' (without the don't care conditions). However, the truth tables of F=A+B and F=A'B+AB' are both very different. Using the don't care conditions should ideally give you a more simplified expression, but WITH THE SAME TRUTH TABLE OUTPUT, right? SO, how does that work here...?
In this tutorial you mentioned that in term of minterm condition we have to take don'tcare as 1 & for maxterm we have to take 0.but it's a little bit confusing to me that when I watched some other videos from different sites they didn't mention anything about minterm & maxterm. they are taking 1 & 0 randomly in term of simplification i mean some times they are taking 1 & somtimes 0 to get the most simplified result,though their function is in minterm condtion. Basically my basic in digital electronics is based on neso academy that's why I need your cordial help to get relief from this confusion.
+Enam Hoque I'm not sure if he is using that as a generic idea, or if he wants people to do that all the time. Personally my textbook says to only use a "don't-care" statement to help satisfy the rules of forming groups. You only want to change a "don't-care" to a 1, if it will maximize your grouping count. For example, he had 2 groups of 2, but he could get 2 groups of 4 if he made both "Don't-care" slots into 1's. So because he could maximize both of his groups he converted the "don't-care" slots to 1's. HOWEVER my book states that you do not want to use a "don't-care" slot to a 1 just to add extra groups to your k-map. This goes against the rules of forming groupings within a K-map. So maximize the size of each group using "don't-care" statements, but do not maximize the amount of groups that you have. Hope that helps.
in quad 1 only b is constant (=1) across all the cells of that quad. So hence B in quad 2 only a is constant (=1) across all the cells of that quad. so hence A
The black box in the figure shown below consists of logic circuit with minimum complexity. The function f(x,y,z) = 1 when x y and f(x,y,z) = 0 when x = y, y z. Determine the simplest logic circuit satisfying the above conditions sir is qsn ko kaise krenge isme dono se same value nhi aa rhi matlab agr min term se kr rhe hai to simplified version nhi aa rha
Hello sir, at 6:17, why did you combine the 1s at cells 4, 5, 7, and 6 all together? I thought that in order to fully simplify a boolean function, all you need to do is to make sure each 1 is part of the grouping and that the largest possible grouping is used and in this case, because there is already a 4 x 4 of 1s formed from cells 3, 2, 7 and 6, we only need to group cells 4 and 5 together and that will result in the minimized function
Thanks a lot neso academy. I just love neso academy. I have a small question over this presentation, pls anyone help,, K map is used for minimizing the boolean expression..viz it requires less gates to design the circuit. But here my qstn is without using dont care condition the result is a x or b And using the dont care condition the result is a or b. Is it same??? For designing the same circuit?? I should know it... Pls help me from anyone...
Sir I have a doubt. While considering quad 2 along with don't care A is one 1 that's fine but even C is not changing from 0 to 0 so how did u not consider it
in this example first K map got the F=A(xor)B and second K map got the F=A+B and hence it is changing the output in the answer F=B+A can you tell me the proper eloborate answer towards this
Helping people pass since 2014....god bless you!!

did you do it?
2024 and still watching you. thank you
I have exam in few days but I 'DONT CARE'!
since you can have either 1 or 0, it doesn't matter {just joking 😂}

You're out here saving lives my friend, thank you very much
After finding this channel, I'm hoping to pass my mid-term exam. Thanku sir
Did you pass it?
My DE mid - semester exam is tomorrow and thanks to you sir i will be able to score good marks.
All the best!

thanks a lot learned 1 month explained shit in my college in just a hour from your lecture your fabulous
fast forward to 2023 , this vid still helping students like me🙌
2024😅
Nobody can give such amazing explaination.
thanks....this video can easily clear our thoughts about this concept
This helps me a lot in my exams thank you so much sir..
I have exam next week and your Digital electronic playlist is helping me a lot.
Thanks sir ,for such a amazing lecture, love from Bihar ❤️
You are very knowledgeable. Thank you, sir!

The first function is A exclusive OR B. The second function is A OR B. Are they the same answer? The truth table for both tells me no.
The only difference within the 2 truth tables is m6 and m7, and as specified, you don't care if the answer of m6 and m7 is 0 or 1. so the expression can be simplified.
OR is A+B.. XOR is A'B+AB'
In next video your doubt will be cleared 😂
Hi me from future...
Seeing your past I am here... 😀
Glad you asked this doubt mate. I'm 8 years late, but hopefully you're doing well in life as a graduated engineer

It felt like watching a movie in youtube sir hats off to your explanation and it's interesting and may I know whether the slides are available for us
I think the answer for quad 2 is F = B + AB, because B is not changing in the quad 2. Correct me if I am wrong.
Same naaku atlaney vachindhi
I don't know what exactly
in quad 1 only b is constant (=1) across all the cells of that quad. So hence B
in quad 2 only a is constant (=1) across all the cells of that quad. so hence A

Thaaaank youuuuuuuu
Thanks man, I am assuming that you assume the don't cares are 0s in cases of product of sums, and 1's in cases of sum of products?
Just watched your lecture before 1 hr of exam 🙃🙃
7 years agoo video, wowww watching in 2021
awesome video........
thank you so much sir
Example was hilarious 🤣
Bring me out vof confusion, thank you

Sir in quad2 A is not change but B is change from 0 to 1 but you say BC Is chnge from 0to1
So, this one is the best example anyone would get to understand the don't care case
good job

Is it same??? For designing the same circuit??

If we take all the don't cares as 1 and solve would it make any difference?
That's what she said!
