The "check-board" pattern can be simplified as follows:
AB'C' + A'B'C + ABC + A'BC' = C'(A xor B) + C(A xnor B) = C' (A xor B) + C (A xor B)' = A xor B xor C. [ A xnor B = (A xor B)']

[@kewtomrao]

For my reference : C is the borrow given to the prev bit and Bo is the borrow asked by the curr bit from the next bit.

Explained 9 years ago but still the goat explained better than my highly paid university teacher

[@Hurricoaster]

In much the same way of the Full Adder using two Half Adders, you can realize a Full Subtractor using two Half Subtractors. Using a K-map, you can deduce the equation B0 = /A*B + /(A_xor_B)*C, and D = A_xor_B_xor_C. The wiring of the Full Subtractor is the same as that of the Full Adder.

[@Hurricoaster]

Also for those interested, C is called B_in in some texts

[@MohammadAhmad-nh5ug]

Why do we use subtractor circuits when we can achieve the same using compliments (by addition)?? Please help.

[@armughanahmed80]

OMG that XOR thing finally made my life easy when you can't group anything in K-MAP. Great video Mate!

[@the_mohan]

can't agree more 💯❤️

[@the_mohan]

also, on a completely unrelated note, I hate logic gates *completely*

[@SreenikethanI]

@@the_mohan lmao

[@Herbus2142]

You can do a substractor by using full adder, inverting B and adding 1 to the operation.

[@SreenikethanI]

so basically 2's complement is being used, yeah?

[@nameisnoxd]

Full subtractor but half 😂

[@geetasaxena2600]

People's said that "old is gold" by watching your video I feel like they are correct
Your are explaining better than our teachers

[@combatfox7009]

Can you explain the Borrow In concept? Is it a fixed value on the table that exist only to guide you to build the circuit diagram?
I mean where do we get that value without the truth table?

last me kya karna tha ? like joo borrow aayega full adder ka uski equation itni hi banegi ya further simply kar sakte hai ?

[@karanjaiswal8890]

What is the ans in borrow if we take only 1 pair of 1's and other two remain alone as your previous lec full adder?
Is the ans is A'B+C(A' XOR B)

[@SAVAGEGAMERYT94]

Yes

[@darshanavaiya4012]

Bo = BC + A̅(B⊕C)
= BC + A̅(Bc̅+B̅c)
= BC + A̅Bc̅ + A̅B̅c
= B(C + A̅c̅) + A̅B̅c
= B(C + A̅) + A̅B̅c
= BC + A̅B + A̅B̅c
= BC + A̅(B + B̅c)
= BC + A̅(B + c)

if the subtraction is in binary how come you are subtracting (2-1 ) to get one which is true for decimal system ?
please clear my doubt

When you borrow it becomes 10 (which is 2 in decimal system)
