Most people watch them though playlist and hence the next one autoplays and the student continue to keep up the flow. Having said that I do agree with what you said.let us take the time to appreciate the good content:)

Where is it?

[@sandipdas007]

does the sequence in state table (qa,qb,qc or qc,qb,qa) matters? if matters then why in the previous video you wrote q1,q2 in state table. plz answer

[@sanomi4492]

Good explanation, but DON'T CONFUSE ME, Neso. In the previous video, you assign LSB and MSB in the opposite way.

[@jillyJoe]

Agreed! this caused me a lot of confusion as well

[@vaishrox66]

This method is correct, he made a mistake in the last one

[@anandar773]

both are correct, u just have to know what is msb bit and lab bit, order doesn't matter as clock applied at the same time to every FF

[@gireeshkumarkancharla4176]

Respected sir bIn previous question two JK flip-flops are taken in reverse order.. Once check this and clarify

[@madhurimadas9635]

Why in this table we considered from C,B,A and not from A,B,C? Because in the previous video you took A,B,C. Please help. Can't understand this.

[@kishaloyb.7937]

It doesn't matter, before writing up the table, you can also go A,B,C instead of C,B,A...as long as you write the bits correctly like 000, 001, 010, 011... instead of reversing the bits, you'll be fine...

[@MrGoumX]

I FUCKING APPRECIATE YOU MAN!!!! UNIVERSITIES ARE FOR THE DUMSTER

[@zaheersuhabuth2677]

i think there is a mistake . you've wrongly interchanged MSB and LSB.please check it

[@prem6748]

In the previous video(2 bit synchronous),should'nt Q1,Q2 be interchanged?

[@alkingshefo]

i have a question what if i did the tables with qa,qb,qc order and i have ta,tb,tc then the output is reversed such qa ,qb ,qc is the correct order from msb to the lsb what you did is just like a reverse order then reverse output i think the output without double reversing is the same. correct me if i'm wrong please

[@nurqistinazulaykha2037]

wow... very neat and simple explanation, but literally makes me understand the whole chapter ..thanks a lot!!! it will be helpful the most in my final ❤❤

[@rahulkhandelwal8781]

is it right to use any of T ,JK ,D ff for any bit synchronus counter ?? did u use t instead of jk here because of reduction in no. of truth tables?

[@gibraanjafar1669]

I think yes . Using T FF is easier because of smaller excitation table . As far as I know we can any type of FF for any n-bit synchronous circuit .

[@aschutadesse1345]

Right

[@raghad5270]

Thank you very much Neso, but I have one question, will it make a difference if I draw the circuit starting from C as CBA instead of ABC or the order doesn't matter?

[@anshsurti3316]

[@tourwithkausik7730]

sir i have a question,, To make a counter if we used JK flipflop,,,can i make this counter with T filpflop?

[@KenSaysHai]

Yes you can 😂

[@kaustubhshankar27]

Does negative or positive edge clock matter in the synchronous counters?

[@shivaniverma730]

Yes, it does . Negative and positive decides that counter will be UP or DOWN

[@kwikersful]

This is a life saver. I spent a lot of time to figure out this problem. Thank you for helping me out.

Sir, I'm facing problem while making it with JK. If u show it in another ppt then it would be better.

what did u became after 8 year of studing from this lecture

Sir/ mam... my question is,, as u explain in your video that we can stop conting on any certain value through nand gate so sir how we can make a circuit which gives output of only even numbers or odd numbers or multiple of individual numbers...?? please pay your attention towards this.... waiting for your response... have a good day..

most of the cases, you take only negative edge triggering flip flops i know we can use positive edge as well but you used most negative edge...Is there any special scenario behind this????

[@samirthegentlewind]

do you still need it? 😅

[@anonymous-gh4mq]

I really understood the concept here. Well taught by you, sir 🙏

[@ediedisonlo]

Great explanation!! Wanna ask why the sequence of the flip flop you draw is in A-B-C? Coz in the table you are writing in C-B-A? Is it a convention to reverse the order from the table?

[@MrCashmasta]

MSB to LSB

[@incharawalvekar3977]

I too have same doubt !

[@sujaysavandv6977]

Because clock is always given to lsb bit

[@mk_annan22]

I took Q1, Q2, Q3 as outputs and drew flip flops with T1,T2,T3 inputs in sequence instead of T3,T2,T1. The logic diagram is just opposite to yours, the AND gate coming in the first FF instead of the last FF. Will my outputs be the same or it will affect the whole circuit?

[@remyaunnikrishnan2037]

evn i have d same dbt

Same doubt but in my university tey hav done like us...so I think so we can do it in watevr way we want

[@TheRegalstreak]

Take care of the MSB and LSB

[@karthi6843]

the main thing is u should take care on msb and lsb

[@akhilgupta3664]

No it will not effect but you have to take care of the sequence you make in ckt excitation table as msb and lsb same will be in ckt diagram.

Hey check anyone did sir did mistake while writing the kmap of QB, QAQC? Should it be 11010101 so the mapping would be 11 only na ?

[@aayushnehra5188]

In 2 bit counter example in ckt excitation table we took states as q1!q2!q1*!q2* and in this one we did the opposite.. So does this affect the counter?

[@kajalsharma8887]

I know it's late...but yes it will affect the counter msb and lsb as when we put q1,q2 then here we have q1 as msb in the table so the output of our counter is such that the 1 FF gives q2 as output and the 2nd FF gives q1 as output to be correct... otherwise u can follow the same as mentioned in this video

[@jatinjain850]

All doubts have cleared . Thank you 👍

[@sanjaysanju0511]

this method is said by our sir for modulo-6 counter but u are using as same for synchronous 3 bit counter what is correct.... our sir didn't explained synchronous counter by explaining on synchronous up counter he said to do all synchronous counter so I checked here but you are making this as modulo8 counter a 3bit synchronous counter

[@DumisaneKuzwayo]

In the exam questions they do not tell us wether to design a 3-bit or 4-bit, so im kinda like confused. Are we supposed to guess in wether to design a 4 or 3 - bit in the exam question?

Sir can u show me the count once ??Like initially 000 then when 1 is applied to T(A) then Q(A) toggles becomes 1 then 1 is fed into T(B) which changes Q(b) to 1 and AND result will be 1 and thus Q(c) also toggles and becomes 111. so How 001. May be I m making some mistake.Can u point me out ??
