Best teacher on earth!!This guy is a genius !!!

[@newbie8051]

Tried implementing the same in verilog.... woah, loved it

Fratello io ti amo, grazie per il video e se passerò l'esame sarà anche merito tuo❤

[@poojashah6183]

Best explanation 👌🏻👌🏻👍🏻👏🏻

[@singhkaptan00]

Thanks for explaining these concepts in great detail. Question :- Is the sequence generator made with the FSM different from the one with the shift registor?

[@ALLABOUTELECTRONICS]

Yes both are different one.

[@hadijaffri9856]

You are an absolute legend. Also I want to ask,what would we do if we were to use a JK flip flop for the implementation. How do we figure out how many flip flops to use?

[@MANIKSINGHprasad]

Great Video Actually !!!!!!!!!!!!!!

[@who.abhinav]

what is name of your simulation software? also great explanation

[@ALLABOUTELECTRONICS]

Its deeds circuit simulator.

[@studymail4800]

hello sire, how to know what to put in the preset and clear of the flip flops in the simulator?

[@ALLABOUTELECTRONICS]

Generally, the preset and clear inputs of the flip-flop are active low. Meaning that when 0 is applied as an input then it will get activated. So, when we want to clear the flip-flops then we should make clear input 0. And we want to make them inactive, we should apply 1. This is valid, considering the inputs are active low. If they are active high, then you need to do other way around. I hope, it will clear your doubt.

@@ALLABOUTELECTRONICS thank u very much, indeed cleared my doubt 🙌

Indeed, thank u very much@@ALLABOUTELECTRONICS

[@markuz5535]

hi, I tried following all the steps for another string but If I try to simulate the circuit It never gives output 1...any chances I can contact you somewhere to share my work?

[@ALLABOUTELECTRONICS]

Perhaps, you might have made some error during the design steps. You may contact me via mail.

[@Kat-zx2je]

thank you so much!!! 🙏

Sir, which software are you using for simulation?

[@ALLABOUTELECTRONICS]

Deeds circuit simulator.

[@bhavanimurugesan9026]

@@ALLABOUTELECTRONICS Is it open source software

[@user-ng8rl3jb1i]

Very good

[@rahulc0dy]

Which simulator is this?

[@ALLABOUTELECTRONICS]

Deeds circuit simulator

[@govardhan8962]

Actually I have one question related to fsm can u give the solution for the question

[@SLUGTHUG]

The solution is the Y output.

Great tutorship 🙏

Which s/w you design and simulator

[@ALLABOUTELECTRONICS]

[@rahulmp4459]

How did you determine the Q1+ and Q0+ ???????

[@ALLABOUTELECTRONICS]

It is written from the state table. For example, when x=0 and present state is 00 then next state is also 00. ( see the left table). According to that, in the second table ( right one), the Q1+ and Q0+ is 00. Similarly when x=1, then next state is 01. So in the second table in the fifth row Q1+ and Q0+ are 0 and 1 respectively. I hope, it will clear your doubt.

[@user-oj1si7ji2n]

If the number to detect is not 1001, but 0101, can I set A, B, C, D to -, 1, 10, 100 like the video?

[@user-oj1si7ji2n]

Or should I set B, C, and D to 0, 01, 010?

[@ALLABOUTELECTRONICS]

@@user-oj1si7ji2n Yes, you should set the states like this only. (B = 0, C = 01 and D = 010)

[@user-oj1si7ji2n]

@@ALLABOUTELECTRONICS Then, how should I set it up when I make one circuit that outputs 1 when 0101 or 1001 is an input?

[@ALLABOUTELECTRONICS]

which sequence you want to detect? 0101 or 1001.

[@user-oj1si7ji2n]

@@ALLABOUTELECTRONICS I'll write the question I'm trying to solve. "The circuit examines groups of four consecutive inputs and produces an output Z=1 if the input sequence 0101 or 1001 occurs. The circuit resets after four inputs. Find the Mealy state graph."
