How to Design Synchronous Counters | 2-Bit Synchronous Up Counter 

Ilove how he knows we're only studying for exams and not to be great engineers or something

I've watched all of these lecutres in order an man I am feeling amazing for my exam thank you so much sir you are a life saver!

ı've final exam tomorrow, you really saved my life dear thanks :)

You have no idea how scared I was because of this subject now after watching almost all of your videos I feel excellent thank you for providing this awesome content free of cost.

I think best part of your presentation is you develop curiosity....

complicated problems to neso academy : am i joke to you great explanation sir thank you very much

Thank you very much prof, I ve watched your video all over again. you ve saved my life

really great! thank you. It's actually very difficult to find simple examples of counters. Most are 4-bit asynchronous

You are the God of Digital Electronics.

These videos make it easier to understand than any book in the market !

wish we had these lectures while I did my BE...but anyway these are so helpful for interviews now !!! thank you so much !

master piece of this concept. No one can find better explanation than this,if they do then they must be dreaming probabily

You deserve to have like million view on every video ! thank u so much

Best tutorials on youtube on this subject. Thank you!

Thanks to the tutor...u r awesome in your way of teaching....I've watched all your videos on digital electronics....and they have helped me clear my concepts...and all probable questions regarding the topic....thanks a lot....thumbs up for ur job....keep making more such videos on more topics...

Sir, u are great...these lectures are helping me a lot...

your teaching style is so good and easy to understand

your explanation is great. your voice and language are really really clear. thank you so much.

this is the first time ..m subscribing anything on you tube...hats off u guys..in none of the books give this as deep as u have taught....really appreciable!!!!

you deserve to have like million view on every video ! thank u so much

I like how he wrote flib flob. It's something i also can't resist to write, sounds so much funnier

thank you much sir!!!!! been saving my digital elec class since day one , I want to put a thank you on all of your videos!!!

Love you Neso Academy!

sir you said is there any restriction on whether Q1 is MSB or Q2 is LSB, bcz in earlier video you treat last FF output as MSB

thanks a lot sir. Your explanation has made hard subject easy to learn.

Crystal clear description

watching these videos at 1.5x speed lol...exam tomorrow ..yup m screwed . ..u are a saviour ..thanks a ton!!

Excellent sir your class are excellent for gate exam

Thanks a lot NESO ACADEMY..The manner in which it's being taught is awesome...speechless

Thank you sir for the knowledgeable content. Sir, a request, kindly make a complete course for 555 timer also.

trust me i am doing eet from a canadian institute but I watch his videos for clarification as my dp2 prof sucks!!

your explanations are wonderful!!! everything is clear, thank you very much

for J1 k-map, dont we have to use Q1 and Q1* ? since our o/p is dependent on those two? and llly for the rest kmaps?

Agar video galat hogi to koi problem nahi sir aap nayi bana do hume koi dikkat nahi hai hume sirf aapse sikhne me achaa lagta hai

2 hours before test. I've miss sooooo many lectures and I am studying whole night on youtube and I am dying : (

Best videos ...best lectures on you tube...😀😀😀

when you simplified using the k' map,q1 and q2 taken as the input.but should it be q1 and q+1?

u r a saviour

Sir, why u r considering Q1, Q2 for finding j1, k1,j2,k2 using k-map instead of Q1*,Q2*

thumb up ... these tutorials make me thirst of knowledge more n more if we r talking abt cars you guys r bugatti 😉😉

It was an excellent lecture. I really find it amazing and helpful 👏.

Nice explanation ! But sir I think in the circuit excitation table, Q1 and Q2 should be interchanged.

When we make the K-map cells for determining J1, K1, J2 & K2, why do we consider the present state values of Q1 & Q2 instead of next state values of Q1 & Q2 ?

u saved me i love u random indian man on the internet

Sir, you demystify DE really well!

well i know what reduces likes is actually those students opening your sessions day before exams and after lockdown ,opening before exam sheet ,, both parties forget to like this video (in state of fear)

hi can u explain the logic behind making the circuit excitation table, i mean why we are doing this thing ? thanks

amazing explanation,sir

I'm definitively a fan of Neso Academy! =D

There is a mistake. You have take FF1 as the MSB. So in the final diagram it should on the right side.

sir can you make detailed videos on identification of symmetry in given function which are very important

thank you sir this helps me lot

3 days for my Endsems , coming from one of the top Engineering institutes in India , but i can say with 100% certainty that only this guy can help me pass DSD 😇🙏 Edit: I passed guys , almost half of my class is up for retest , ese paper was very tough 😭

I typed it wrong sir the previous one i.e instead of using Q1 and Q1* for finding j1 using k-map u have used Q1 and Q2.why sir ? Would you please help me in this aspect

You make this very simple!! Thank you so much for the efforts! you're a gift from God lol

you explained wrong Q2 must be in place of Q1. you should correct it

Thank you sir

thank you , you saved my life

wonderful explanation sir!!. but can we design a counter using a d flip flop?

Can you please clarify is this up or down counter because the MSB and LSB interchanged so output equation also changed

good explanation!

thanks so much you helped me before 2 hours exams lol

Play it at 1.75x and it will save your day

the final diagram is wrong.You have considered Q1 as the MSB throughout the entire video. But in the end, you drew the diagram Q1 as LSB. The flip flops should be reversed.

U are so good. Thanks a lot😊

thanks a lot i got so many information from your lectures

Thank you sir 🙏🏼

Thanks sir. From Kerala❤️

For people getting confused about MSB LSB!. It is a "synchronous counter" i.e one flip flop doesn't depend on the output of the previous flip (getting clock from the previous one) like in async counter!. So initially he took q1q2 (with q1 as MSB) and he did the procedure with the same! and in the diagram eventhough he drew q1 first and q2 second EVEN if he drew q2 first and then q1 IT DOESN'T MATTER!! what matters is what YOU CONSIDER AS MSB. So if q1 is initially considered as MSB then in the FINAL the same q1 MUST be taken as MSB and fed to some other circuit (perhaps?) but the representation doesn't matter!. ALTHOUGH things would've been clear if he had taken q1 as q2 and q2 as q1!. Ask me any doubts if u have!

Thank you so much sir

subscribed for this one.

Nice explanation Sir... 👍

The ff numbering in the circuit is wrong. It'll ber 2 no. ff in the left and 1 no. ff in the right. Isn't it?

Sir I don't know why but I think there's a mistake in step of k-mapping, you didn't differentiate Q1, Q2, Q1*, Q2*

Wow Sir! I am from a famous uni (Top 15 QS ranking)...and I must say you are much more efficient at explaining these DE stuffs than my profs!!

please make vedioes on computer organization and architecture

I have an exam and rn binge watching hell ya...

you make everything easy

In your circuit diagram, You've shown Q1 as LSB, but in the excitation table you're using it as MSB. Please correct it.

thanks RU-vid and this tutorial it help me lot for clear my douts

Explained very nicely....

THANK YOU SO MUCH THIS REALLY HELPED ME :)

why we use mostly J K flip flop on counters?

i cant shake the feeling that im being scammed...loving this explination though it helped alot:)

Really Helpful thanxx sir

How can i create A 4 bit synchronous Counter using JK Flip Flop? Can you please make a video on that! I am facing difficulties at the last table.

Thanks a lot sir :)

your videos are really helpful. Thanks for spending time making the videos :b

i am unable to understand , how u r drawing the excitation tale of flipflop(step2), what is qn ad qn+1??

great stuff👌

thank you

GREAT!

Nice explanation thank you

You right I was on my exams

Amazing ❤

Thanks a lot sir It was very informative and useful.

Very goood video! U make my life. have a question: why the analog circuit is not updated? :(

to design a counter we need a toggling condition which is present only in t and jk flipflops then how can d flipflops be used for designing them?

Thank u sir

Thanks ❤
