I don't understand what borrow in is, since binary subtraction, I don't get it. A = 0, B = 1, Bi = 1, A - B- Bi = 0 and Bo = 1, but where is that Bi coming from... The only way that I understand the process is considering this a 3 bit subtractor instead of 2 bit.
Dear follower of neso channel Do as homework Demux try 1:4 using 1:2Dmux. Similararly 1:8 using 1:2 Demux. Special case 1:8 using 1:4 Demux with enable and without enable. Tnx #neso sir...
In previous lecture he told that in this lecture we are going to read DEMUX tree but here he is teaching about Full Subtractor. Is there any other place that he had taught DEMUX tree?
Just do the revers of what we did in the multiplexer tree thing.. for a 1:4 Demux using a 1:2 Demux take a single 1:2 demux first (Select Line S1) and then 2 demux (Select Line S0).
Is borrowed input considared the same as a any other normal input(like A or B) or does it have a special signiface?For example,Half-Subtractor uses 2 bit input,Full Subtractor uses a 3 bit input.Does naming it Borrow Input(bi) or C make any difference?For example,if i have a 5 bit Subtractor will 1 bit have to be named Bi and 4 A,B,C,D or can i just name them A,B,C,D,E.(Im not sure how a 5 bit sub is made yet since i havent checked it out. I know this may be a weird question but it still kinda bothers me.
After your lecture, it was extremely easy to build a full adder using a demultiplexer. Thank you!
How did you embed a link in your comment!!!
Superb.......!!!! It was a smartest skill of teaching ever seen.....you taught it in very easy manner
sir it wasnt easy before i listened from you but now it is thank you

He used an Or gate, since D= Y1+Y2+Y4+Y7
yes
It is due to the minterms, as they are Sum of Products, or in this case D = "Y1 + Y2 + Y4 + Y7".

Tnx #neso sir...
Legend ❤
why didnt we use kmap as we did for full sub using muxes ?
Sir thanks a lot for ur videos... It is so much helpfull.. And you explain very well... Thnaku so much sir..
Good bro . Helpful video.
Thanks a lot... Nice explanation
Really helpful.Thank you so much

Is there any way to understand what kind of DEMUX I need to use for implementing this operation???????????????????
why did you not use enable here, but you used it in 1:4 and 1:2 demux?
Sir we can implement two 1:8 demux individually for the differ(D) and borrow(B) as we did in the lecture `full adder using 4:1 Mux `.
we can do. But it is not the efficient way.
Sir, why do we always use OR gate?
In this case, why didn't u use Enable i/p?
If we look at the output, is is equal to 1. Hence we can say that 1 can come from either Y1 or Y2 or Y4 or Y7
sir what is the difference btw demux and decoder???

Sir please make a video on implementing 1:8 demux using 1:2 demux
Is it possible to design a full subtractor using 1.4 de mux
Please answer...
Thank you
@@arpitasaha8425 is it possible?
Is it possible to design full substractor with 1:4 DEMUX?
Please reply sir
I think it is not possible
Could you explain how you determined that D and B_0 could be produced via OR gates from the demux outputs?
Thanks
go to the lecture of full subtractor you will understand
Can we use two 1:8 Demux one for borrow and other one for difference
Why not bro?? U can but in real world we try to simplify our problem as it will require lesser hardware and so it will be cheaper.
Why can't we shuffle S⁰,S1,S2 them or take in other order?
Can we make full adder using demultiplexer
thank you so much bro :D
Thoda audio bdao sir ji, request hai🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
@@swastikmohanty7370 i fixed it ( :
sir can u give video about full substractor to 1:8 multiplexer.
demux treee
Why we are using the OR gate?
Because in SOP we use 'OR' gate if the same question would be solved by POS then we would select 0 as high value and will use AND gate.
If my collage teachers also teach us like this then i can save penalty of time
post a video of 4 bit subtractor adn comparator using 1*8 DEMUX
tq sir
u should use negative input of OR gate or NAND gate
please upload full adder using 8:1 multiplexer
Why we use or gate?
Sop form..minterms we are considering.. summation u can see it in video
IF INPUT IS GIVEN 1 THEN IT BECOMES DECODER.
why are you using only or gate
If we look at the output, is is equal to 1. Hence we can say that 1 can come from either Y1 or Y2 or Y4 or Y7
It is nice.
What is Bi
borrrow input
Can u do this for 3:8
there is no such demux bro
Demux tree??
sir video on demux tree is available?????????????????????????????????????????????????????????????????????????
looking for the same thing
"100Thanks"
Make a play list
Neso Academy demux tree pls
Like if u r from k.j Somaiya poly
