- A Digital Practical Experiment to Show the working of a J-K Flipflop using Clock and NAND gates. A complete explanation of the Practical Circuit with verification of the Truth-table is shown here. J-K Flipflop is a Sequential Logic circuit.
In this video, I have discussed each and every step for implementing the circuit using a breadboard and the necessary discrete components for better understanding. I have used NAND gate IC - 7400, 3 INPUT NAND Gate IC -7410, LEDs, resistances, and wires for connection. Go through the entire video and you will be able to solve other Digital circuits very easily.
These videos are beneficial for Undergraduate (UG) and Postgraduate (PG) Physics and Electronics students and even helpful for NET, GATE, TIFR, JEST etc examinations Preparation.
LECTURE 3 Paper Code : CC13 , SEM - 6TH ,
Paper - Digital Electronics

আপনার বর্ননা করার পদ্ধতি খুব সুন্দর। ❤ , ধন্যবাদ ম্যাম। আপনার সুস্বাস্থ্য কামনা করি ❤
Thank You so much..
Your feedback is valuable to me..
You too take care 🙂
wah bhai wah
Aap ne dono resistor 220ohm ke liye hai n?????
No..it's 1kohm
Circuit is not toggling properly whenua clk = 1,J=1& K= 1
I have used a Nand Ic to perform the experiment and as You might be knowing Q in the truth table denotes the position of the next state. In my circuit, the next state is shown with the help of a white Led connected from pin 3. when I performed J= 0 and J= 1 condition, my Q i.e white Led which was glowing got off denoting Reset condition and hence red led got on denoting the bar condition. Now when I perfomed J= 1 and K=1 condition The position of Q that represents next state should show toggling by getting on and off on application of clock pulse . As a result, when clock pulse was applied Q got on and with subsequent clock pulse it got on and off, and that I haven't shown here.. I just recorded a video for 4 pulses ..once you repeat the pulses You can see the changes of the retained previous states in both the LEDs. I hope when you perform the experiment in the lab using this circuit then you can understand more clearly.
@@VICTORIAPHYSICSMam toggle should be shown else what is use of jk, use SR.
Hi everyone ..check out the new GNUPLOT TUTORIAL SERIES on my UA-cam CHANNEL VICTORIA PHYSICS.

May I know the value of the resistance?
I have considered 1K ohm resistance here..
