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!

[@isyardisknder8534]

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

[@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!

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

[@josephhaas3360]

[@bananskalsvensson]

Thank you so fucking much. Best video on this site. No bs, just exactly what I needed

[@AK47_414]

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!

[@pat022860]

you could be the only one on youtube that could explain that

[@joehaas0]

Thanks so much for the nice comment!

[@minidupradeeptha4673]

Thankyou very much

[@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)

[@pamp3657]

good video thank you

[@joehaas0]

Thanks so much for watching!

This video was created to save my life from the digital class.

[@josephhaas3360]

Thanks so much!

Thank you 🙏🏼🙏🏼🙏🏼

[@abdulghani9596]

This is positive

[@electronx99]

**positive edge triggered JK master slave flip flop with preset and clr and thankss

[@abunawenow8696]

@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.

[@alisoleiman7166]

Thank you 🙏🏼🙏🏼🙏🏼

Awesome thank you!💕💥💥💥💥

[@joehaas0]

Thanks so much!

[@marissaklimkowski5472]

THANK YOU!!

[@eldon3384]

Thanks man all the best

[@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...

[@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

[@mirtahir6436]

Keep going sir

[@dilayiremuludere921]

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
