If you closely observe the circuit, then the output of the first flip-flop is connected to the clock of the second flip-flop. And the flip-flops are edge-triggered. So, they will respond to the input whenever there is a transition in the clock. (When Clock goes from high to low and low to high). So, here the second flip-flop will respond whenever there is a transition in the clock signal. And it will happen whenever there is a change in the output of the first flip-flop. In other words, whenever there is a high-to-low transition in the output of the first flip-flop. The same is also evident from the timing diagram at 4:46.
Need correction, few things were explained wrong here. for the down counter we need to take the clock pulse from the Q to the other ffs. and for the up counter we need to take the clock pulse from Q(bar) to the other ffs.
It depends whether the flip-flop is positive edge triggered or negative edge triggered. I think you haven't watched entire video. At 12:38, I have already provided table for the connection for both positive as well as negative edge triggered flip-flop. And its humble request, please do not misguide others before fact checking. Don't get me wrong, I do appreciate if someone finds genuine mistake, as it is helpful to the viewers. But some times such comments misguides viewers, especially those who are watching the video just one night before the exam, where they do not have time to check the facts.
Excellent information.... Being a mechanical engineer, which book would you advice for grasping the concept from beginner to the expert level? Also, by just understanding your videos, do we need any book or are your videos sufficient? Thanks. Thanks.
Hi, if you want to learn the basics of electronics, then you may refer this book. Electronics Principles by Albert Paul Malvino It is a good book for understanding the basics. Along with the book, you can also refer the basic electronics playlist on the channel. Here is the link for that playlist: ua-cam.com/play/PLwjK_iyK4LLCAN5TddEZyliChEMpF0oOL.html
2 bit down counter using negative edge triggering is already covered in the video. (See the chapters in the video). You just need to add one more stage in the configuration for 3 bit counter.

Sir, great videos...
Much helpful 🙂
The best video i watched for counter is this , thank u very much💗💓💗💝💖
Really nice explanation
Very well explained
3:12 sounds like "working of the stupid ripple counter" 😂
just love it..all clear 🤩
What about from where to take output Q or Qbar
شكرا على الترجمة بالعربية❤❤❤
at 7:43 at first clock transition how the input of Q1 changed as at first clock transition due gate delay the q bar output is not avaliable
Wht is meant by transition in yhe output of flip flop? As u said in 2:17.

Hello man, welcome to you.
Very nice 👌👍🙏
At 10:30 is this table valid only for asynchronous?
Yes
hello, nice explain
Thank You❤
12:20 how do you fill up the table ?
At each rising edge of the clock signal, just see the status of Q1 and Q0. You will be able to fill the table.

Is it compulsary to learn or operate synchronous and asynchronous counters in negative edge triggered mode only??
No, you can also use them with positive edge triggered flip-flops.
excellent lect

@@ALLABOUTELECTRONICS Thanks for your kind reply. Keep it up...
can you show the 3 bit ripple down counter with negative edge triggering
2 bit down counter using negative edge triggering is already covered in the video. (See the chapters in the video). You just need to add one more stage in the configuration for 3 bit counter.
nice sir
helpful
Where is explanation about UP/DOWN counter? And it's truth table?
