JK Flip Flop Timing Diagrams

[@alghamdiyusuf]

I've been wasting my time reading about it for days and you just explained so beautifully in 6 minutes. thanks so much Joe!

[@joehaas0]

Thanks so much for the comment! Glad to help!

[@Hitsukaaaaaaa]

right! This video is very very helpful. I understand how it work immediately after watching this video. Thanks

[@zawayne8952]

your explanation makes it easier to understand timing diagrams, couldn't have been more simpler

[@joehaas0]

Thanks so much🙂

[@Miguel-zl7cs]

This video is the best, I wish he spoke Spanish, but it doesn't matter.

[@joehaas0]

Thanks so much!

[@bananaa1867]

Thank you so much, you are a lifesaver. My professor decide to do last minute exam about this JK flip flop timing and I stumble upon this vid and it helped me so much.

[@joehaas0]

Thanks so much - glad to help!

[@alec6310]

video just saved me 30 min of reading a slideshow, thanks m8!

[@josephhaas3360]

Glad to help!

If I had educators like this, maybe i wouldn't be so garbage and stupid at electrical engineering

[@joehaas0]

Thanks for watching.

[@rawarori]

you explained in 6 minutes what my lecturer couldnt in 30 slides

[@joehaas0]

Thanks so much for the great comment!

[@KeViNkErR93]

Basically taught me in a few minutes what its taken my lecturer 5 lessons to attempt to explain!! 🎉

[@josephhaas3360]

Thanks so much for the nice comment!

@Joe Haas .. I"M I the only one who noticed the mistake with the second example? or please correct me if i"m wrong.
With the active low, our output will be activated when the input is "0" . But he went on seting and resenting, using the active high format. Please correct me if i"m wrong, but i"m pretty sure he made a mistake there.

[@joehaas0]

Thanks so much for the comment. I am pretty sure that I did the second example correct. With the active low, I am setting or resetting when the clock goes edge goes from 1 to 0.

[@abunawenow8696]

@@joehaas0 Ok thank you for the review. i will watch it again. Theres something i should be missing.

[@Ezraielshayan]

Thanks a lot champ

[@indianentertainment2718]

Thank you ❤

[@eldon3384]

Thanks man all the best

[@oluwademilademustapha3637]

Hi! What about if reset is synchronous?

[@joehaas0]

A synchronous reset would "reset" the flip-flop on the next clock pulse.

[@oluwademilademustapha3637]

So if it is deasserted at the rising edge of a clock it won’t take immediate effect on the Q pin until the next rising edge?

[@joehaas0]

yes - synchronous inputs will only change the output Q on a rising edge (assuming positive edge triggered flip-flop)

[@oluwademilademustapha3637]

Ok thank you so much! Just to clarify sorry for so many questions I just really want to make sure I’m on the right track xD If the synchronous reset is active on the rising edge of the clock does the Q pin go immediately low?

[@joehaas0]

yes - the synchronous reset will make Q go low on the rising edge of the clock (assuming positive edge triggered clock)

[@DangQuocNhut]

Thank youuuuuuu. omg

[@joehaas0]

You are welcome! Thanks for the comment!

[@rafaelpalmones9309]

you just saved my ass thank you so much bro

[@joehaas0]

excellent - so glad it helped!!

[@dudesdudes8957]

hello, i'm curious how did you draw the diagram, which program did you use? I need it for my homework.

[@joehaas0]

Honestly, I think I just drew lines in a Microsoft Word document. It was a long time ago.

[@dudesdudes8957]

@joehaas0 thank you for your answer🙏🏼

[@merilliapridayriskiana8777]

Esti bine venit. Mulțumesc!

[@yourgirllebogang]

Thank you for this

[@joehaas0]

glad it helped!

[@azizmorad8083]

there is maybe a mistake in the last seconds of this video when the teacher has set the output at 1 despite of the set and reset are 1 anyway thank u

[@bbushong67]

You're correct. The very last negative edge would take Q low due to a synchronous reset...

[@alisoleiman7166]

Thank you 🙏🏼🙏🏼🙏🏼

[@lody-loyd1525]

So what's the difference between 'Active hi' & 'Active lo' if they both toggle switch @ J=1; K=1 & memory only @ J=0; K=0?

[@Hella808]

for anyone who needs this, it just clock triggers when the clock signal goes to '0', instead of the active high that goes to '1' @4:30

[@pamp3657]

good video thank you

[@joehaas0]

Thanks so much for watching!

[@saisathvik3587]

just wonderful. saved me a lot of time reading about this.

thank you wow

[@dilayiremuludere921]

Clk yazan clock yerinin önünde yuvarlak top varsa negatif edge demek aşağıya doğru olan 1 den 0 a gidenler. Ama yoksa top falan yukarı doğru giden 0 dan bire bakıyorsun

[@dilayiremuludere921]

@Acss47 bahsedeyim ama pek bi bilgim yok açıkçası eğer üniversitede ve benim gibi digital dersinde görüyorsan bunları zaten senkron olarak görüyosun hep asenkron bize göstermediler maalesef
