The reason why we don't use Kmap here is first of all, inputs are not binary. For the previous lectures, we could use K map since the inputs were in binary form. Here the question itself gives variables in decimal form. Therefore, we can only set them one by one to the variables. Of course, we can simplify the circuit by designating each decimal variables to binary and use only 4 inputs and 2 outputs but thats not the question here. This is what I've figured out. Plz comment me if i am wrong

[@davidisaacgalang3000]

Thank you, tho late but I was just about to ask that

[@TrueDetectivePikachu]

Bruh! I thought encoders where something super complicated till I watch this vid, its literally a meme. I guess that with that one could just hook up this encoder to a 4-bit comparator and prob have a functional lil system on verilog or something idk. This really clears a lot of my confusion, thanks Neso Guy!

[@reyfoljamesgarcia4790]

Hello Sir, Output B should be 2,3,6,7. (in the photo) Also thanks for the videos, It helps me a lot.

[@pavanfernandes9329]

Yes

[@aslampt9367]

In the implimented diagram copied from book, the connection point to the OR gate -B is not correct.Please correct it

[@anaghbasak]

Actually we can go upto 15 from 0 using 4 bits, however bcd uses upto 9. Which is 6 less than the total capacity that can be expressed using those 4 bits. So the rest are just don't care conditions and we should not really put any effort in caring about them.

[@siddhipharate1567]

Thankyou so much it was really helpful

Hello! What Program are you using to draw for this video?? Great Content! I love visual learning , it helps me more than books. Subscribed!

thanks ....ur videos really helped me in my exams

[@daniaamir4806]

how we can find number of outputs in Decimal to BCD encoder

[@sahasona9718]

Convert the Decimal No. 35 to Binary and Gray Forms and design the Relevant Logic Circuit for implementing the Binary and Gray Interconversion of the given Number. Please tell how this problem solution

[@aritraghosh8152]

sir how the relationship between n and m is maintained in Decimal to BCD Encoder??

[@vinaysahotra5259]

2^m outputs are maximum outputs .relation outputs

[@gamar1226]

You can use BCD to represent numbers from 0-9 so that is 10 inputs. The other 9-15 are don`t cares.So in total you should have 16 inputs and if you use the n=2^m rule you ll have m=4.I don`t know if you add the other input lines they will float or it doesn`t matter if they are or not there.

[@devubs4416]

Simple and powerful 👌👍

[@shpsi]

what about other 6 inputs bcoz in encoder 2^m=n. m=4 but here n=10. are they free

[@srisushma]

In encoder,there r 2^n inputs->n outputs right? So when there r 8 inputs, outputs must be 3 (2^3)isnt it ?

[@akashbisht22]

Now this may be a silly question. But this thing is not getting in my head. How can we use Decimal No.'s as an Inputs to OR Gates? or are they just Lines in sequence that have no.s written on it which can take value as 1 or 0? Somebody help me!! :D

[@alphasatari]

They're lines which can take 1's or 0's arranged in sequence 0,1,2,3,4,5,6,7,8,9. Let's take an example if you make 7th line (i.e. 7) from left HIGH then output C B A will be high automatically representing output as 0111.( D is low) Did you see? Just by making a single line HIGH all other inputs of gate become HIGH which are associated with it.

[@satakshi0304]

The relation between number of input lines (n) to number of output lines (m) for encoders is n=2^m. Doesn't Decimal to BCD encoder follow this rule?

[@Biggie.Cheese.]

Yes I also have the same doubt..... *****

[@vidyavarshinip.vvarshini3744]

+satakshi030 it doesnt fallow in this case becouse no of bit diffres so

[@abhishekmukherjee2091]

But according to the rule it can't be done so

[@CoolCool-jp4hv]

The number of inputs 10 is not some power of 2..we can't take 3 outputs as for that we get 8 inputs.. So we take 4 outputs.. We can get 16 inputs... 10 are required.... I think so.

[@tiasmondal7909]

@@CoolCool-jp4hv you are correct because the numbers from 10 to 16 are taken as dont care but we consider 16 numbers as bcd code. Hence, for this reason we take 4 outputs for 16 (0 to 9 and dont care conditons included) inputs

[@swarupdas4139]

Which book we should go through? ? Which one you wiil suggest for digital electronic??

[@saikarthik002]

why dont u use the kmap and minimise the expression

[@sundersingh2736]

In the implementation ; B=2+3+6+7, btw in circuit there is input of 2,3,6 & 5 to the OR gate ...is it circuit correct or incorrect???

[@omarmahmood4209]

The circuit is incorrect.

[@civilconcrete172]

Bro I love Neso Academy

[@UECAshutoshKumar]

Thank you sir

[@fatimaahmad2657]

why you write A,B,C,D in D,C,B,A in table

[@ibzih]

from highest (left) to lowest (right) priority

[@gagandeepshergill9153]

what about the relation n = 2^m ?? The no. of input lines are not satisfying this relation.

[@abcdef1a214]

[@tanvipirramba782]

sir..can u please add a video of quine mc cluskey method with dont cares!!!!

[@lakshita8386]

this one doesn't abide by the m and n relationship you defined in the previous video. why?

[@BEC_MdWaqarTabish]

for B the circuit connection should be in 6.7 instead of 5&6.

[@thefive.am.c]

Do bcd and binary mean same ???

[@shayanfaisal9012]

No

[@NirmalyaManna]

Nah bro....wtf

[@abhimanyujena191]

for encoder input=2^output but here input is 10 and output is 4......input should be 16?????

[@usama57926]

thank u brother

[@razaanwar6754]

Can The order be in any way like ACBD or ABCD or DBAC

[@Hasan-pc4hy]

why o/p lines are 4 having 10 i/p? Bit confusing.

[@golu-kk4du]

Bro literally this video post 9 years ago

[@GAMING_SHORT_57]

😮

[@subhradipmukherjee5440]

the no. of inputs are 10 and outputs are 4 how is that possible because 2^4 is 16 so there should be 16 i/p
