@@patrickshenton769 WOW! Now that is what you call racist and prejudice and stereotype. I am from the Caribbean which is predominantly black. I happen to teach computer science at a college here. I have seen many blacks naturally master computer science and math in no time! Don't repeat your thoughts anywhere else because it makes you seem naive! Black people have been put down in making us think that we are no good. Then we realized that we can dominate or do well in sports and other areas with talent and the right support. Now we are branching out even more because we realize that the sky is our limit.

We can reach the second equation of Co from the same K map equation. Co= AB + AC + BC Co= AB + AC(B+ B`) + BC(A + A`) Co= AB + ACB + ACB` + A`CB Co= C(AB` + A`B) + AB {As ,X + XY = X, Here X->AB, Y-> C, Therefore AB + ACB= AB } Co= AB + C(A xor B)

[@pedromendes6846]

To understand better the truth table, write it in this form: Ci A B | Co S Then for example if you have something like 1 0 1, for Ci, A and B respectively, just add the amount of 1's, in this case, there are 2, and write that number in binary, so it's 1 0, for Co and S respectively.

actually this is a binary addition when it comes 1 1 it does not mean 2 it mean 0 and 1 where 1 is carry and 0 is sum

[@pixmasterstudios5623]

Because I guess professors well most of them get bored teaching the same stuff over and over. They grow impatient, they just want to quickly get over with it. Only some professors are passionate, they teach everything with the same enthusiasm as if they're teaching it for the first time.

[@vizviz72405]

They teach just for completinh course and getting salary

[@divyanshujhawar3671]

There is an easy method to find the carry expression by using the standard K-Map procedure. Once we got the expression C = ab + bc +ca , then use the property -> ab = ab(c + c') and use this in all the three terms and combine them with others. It's quite a bit easy.

[@spavithran997]

thank you bro!

[@kushshukla6588]

How?

[@sawazalz9764]

​@@kushshukla6588 This might be a late reply, but to do this you need to apply it to all and expand them all. Here's how: C = ac + bc + ab C = ac(b+b') bc(a+a') + ab(c+c') C = acb + acb' + bca + bca' + abc + abc' C = abc + ab'c + abc + a'bc + abc + abc' group all the abc C = abc + ab'c + a'bc + abc" C = abc + abc' + ab'c +a'bc factor the ab and factor the c C = ab(c+c') + c(ab' + a'b) C = ab + c( a xor b) There you go

Hi Sir, thank you for these videos, they have really helped me in understanding combinational circuits. One question however, not sure if this is youtube's default mechanism, but the videos in the combinational circuits playlist seem to be in random order. As such, I find it slightly difficult to follow some videos due to a lack of contextual knowledge, only to realize that the supposed previous videos has been placed in the later part of the playlist. If its not too troublesome, could you indicate the order of the videos that should be watched? Meanwhile I'll try to watch them in the order that seems logical to me. Once again, thank you for your efforts!

[@saimoon4232]

what's the order that you found reasonable? pls indicate here. I have finals next week

[@yarenkaya7872]

For whom wonders the algebraic proof for finding Co, we just need to add another AB to the second equation. It turns out that AB+AB+A'BCi+AB'Ci We can combine the terms as follows : (AB + A'BCi) + (AB + AB'Ci) = B(A+A'Ci)+ A(B+B'Ci) = BA + BCi + AB+ACi = BCi + AB+ACi By the way, thank you for the tutorial

As a faster leaner 🎉 1+1 = 10 which means 0 is a Sum then 1 is Carry . 0+1 = 1 here the sum is 1 then the carry will be 0 1+1+1= 11 it means that 1 is a Sum and other 1 which remains is a carry . 💻💻💻

[@flyinghigh3433]

Thank you

[@martinalber5054]

there are 2 possible expressions for Co: Co=AB+Ci(A+B) Co=AB+Ci(A XOR B) Looking at the Karnaugh maps it seems the 2nd expression would have the shortcoming of generating glitches, while the 1st expression would not and it's safer. Why is it chosen the 2nd expression ? Note: glitches are generated when the groups in Karnaugh maps do not overlap

[@furkanaltay7947]

I think you make a mistake grouping items at karnough map Co=AB+Ci(A ex or B).Because if we take groups just like you show us ıts became something with C compliments

[@nishithaanchan8382]

best conceptual teaching

[@ericbelrose1984]

If I understand everything correctly you do not need to do the last karnaugh map. It is still correct if you have: C_o = AB + C_i(A X+ B) (I used X+ for X or), but it is also correct if you have C_o = AB + C_i(A + B) and that is seen by using commutativity from C_o = BC_i + AB + AC_i. When you regroup the terms C_o = AB + BC_i + AC_i which is C_o = AB + C_i(A+B). In fact I would say that the Exclusive Or is technically incorrect since it implies that if A and B are both 1 then C_i = 1 then the result is 0 which is not true. Unless I've misunderstood something.

[@ericbelrose1984]

Therefore if the text says C_o = AB + C_i(A X+ B) it should be viewed as incorrect. That expanded is C_i AND (A XOR B) which is 1 AND (1 XOR 1) for the last line of the truth table C_o should be 1, and yet if you AND that expression it is 0.

[@ericbelrose1984]

I think actually it would still be okay because the AB covers the ABC_i, but AB + C_i(A+B) is no less correct. So correction to my statement it is incorrect.

[@ericbelrose1984]

Also if you take the circuit diagram for Full Adder it is the way you have it Explicitly. It is a simpler design when you are doing both sum and carry in the same circuit.
