8:09 my facial expression when learning these stuff.
🤣🤣🤣🤣🤣🤣🤣
Nice🤣🤣
😂😂😂😂😂😂😂😂😂😂😂😂😂😂
comment of the decade
LMAO exactly
how did you obtain the original state diagram, from the circuit?
did you get the answer bro?
@@nihanthbaratam9554 did you get till now??
Amazing.!I've never understood anything this clear in classroom..thank you so much nesco💕
thanks to you, I've got 97,5% in my last test about Digital Eletronics(FF, Latchs and State Machine).. HUGE THANKS TO YOU !
How to make that state diagrams... Can u any1 hlp?

can you explain how will you take i/p and o/p values??
hey team,
for the PS 00, if input is 0, then NS is 00 and output is '0'. For PS 01, if input is 1, then NS is again 00 with output '1'. Then how in the Moore diagram only 0 is written as output inside the state?
I wanted to ask similar question, but your question is confusing me
Plz can u explain one more time "how u clarify moore diagram 0/0, 1/0, 1/0 and 0/1
8:42
the output here should be 1 according to the machine on the left, there should be a new state for it
All your videos on Digital Electronics are superb and are really helpful. But this one is quite confusing. Especially the state diagram part. Please do a new video on this with proper explanation.
i like all the videos of Neso Academy which are for EC stream All topics are covered and explained in a very simple and comprehnsible fashion.
thanks alot!!! you are lectures are just awesome!!! i was just afraid of TOC bt by studying through your lec i started feeling TOC easy... once again thankyou n i shared your vedios to mine friends n they too liked it.
please explain how i/p and o/p are taken for state diagram
+Prince Mahesh Actually he is not using any kind of logic while calculating output. He has chosen inputs and outputs randomly.
how can a person actually taken the i/p and o/p ?
@@advaitharmy
He didn't explained how to take I/p n o/p
Transitions in example are random, but if you want to do it correctly you just find what happens for each combination of state and input.
For example if both flipflops are set to 1 (Qa=1, Qb=1; state "11") and you put A=1
Then that will make Ta = (1 and 1) = 1 so left flipflop will toggle at falling edge of the clock pulse; Qa changes from 1 to 0.
The right flipflop receives Tb = (0 or 0) = 0 and so it will not toggle; Qb remains 1.
(Tb is affected by the PREVIOUS (starting) value for not(Qa) and not the new one, because the new one hasn't yet traveled through the wires)
>>>>>>>>>>> state 11 changes to 01 if A=1.
etc. for the other 7 transitions.

awommm.neso....u.r the heros man....i never yet cleared my concpt....u r the reason behind my each DIGital electronics concpt....
what about the output of the lines representing the change of state
Which software did you used to write those things in the black screen? It's beautiful.
I didn't understand the original state diagram, how we get that diagram?
Yes I too
U can watch in this zeynep
th-cam.com/video/NNOSWnTHakY/w-d-xo.html
@@yerrollasharonpriyanka1252 he said "randomly completed"
Please I didn’t understand how you made the state diagram. I didn’t really understand how the outputs was generated. Could you please explain how they were been generated?
Thank you!
stanley boakye same as me 🤦🏻♀️
How did you decide that while going from 00 to 11 if the input is 1 then the output will be 0 ? and similarly other decisions ?
facing the same problem
at the "01" to "00" transition the 1/1(input/output) is written as 1(input) so the information 1(output) is lost in moore machine
I guess since its 0 and 1 it should be a don't care condition and he should have written x
Sir i have a confusion.... You mentioned next state is stored in memory 03:18 and then you said 03:32 that present state is stored in memory
U have great explanation skills for bunch of other videos which I cannot see in this video... how come you have written the original state diagram randomly?
it's not at all clear about how are you taking one as input and output
how did you draw the original state diagram ?
Can anyone explain me how he gets the original state diagram of moore state machine
Subah end sem hai , it's 2 am now and here I'm watching everything in 2x 😂
There would be something wrong in the state diagram (2 T flipflops). If the state is 00 (Qa=0;Qb=0) then the output would be Y = 0' + 0 = 1. But you wrote that in state 00, output is 0!
That's not state diagram for above t flip flop sequential circuit but it's a random state diagram
Sir , How you draw the state diagram in this example kindly provide brief explanation?
th-cam.com/video/XNAK-L7NlOM/w-d-xo.html&start_radio=1&t=1
What if there is no same state in the diagram. What r u going to write under the state?
sir plz make video lectures for memory & mashines and also for digital logic family
Sir, What would be the output in Moore State Diagram, if any previous state has different output at the different input? for eg. let the 00 state has 1 as an output if the input is 1 and 0 if the input is 0. then what will be the output for Moore state diagram?
Same Doubt
U know how to handle with that complex logic circuits Thanks hope lessons help me to pass the class :D
thnx a lot sir...these videos are really vry helpful for me...
Sir, if possible please provide lectures on Memories and Logic Families
Thank You : )
Clear explanation, but I have something to ask.
On the state diagram, 01 circle, it has 1 as an output. But from the 10 circle, there is an arrow with 0 inp and 0 outp to 01 circle. How can it be, since the output is 0 but it's already written 1 as an outp in 01 circle.
Thanks
same doubt here
SAME DOUBT
same here is contradictory, i believe the output from 10 should be 1/1 and the output of 01 should be 1/0, then it will converge!!
Same doubt
Here ,it is just a procedure to convert a state diagram to Moore state diagram ... You have to put the output of the state in which the nextdoor state is also the same state and neglect the other outputs
can someone explain me states of input and output?i can’t understand.
how can u say the output does not depend simply by writing equation o/p=Qb'+Qa,
As Qa might be depending on A,therefore output depends on A right
bhai usney bola directly depend naho karta hai
sir suppose in the original state diagram for state 00 , for input 0 is output is 0 and for i/p 1 output is 1 then which value should we write in the equivalent moore state machine diagrams circle?
Can't understand the state machine diagram ip and op
Please how did you get the output bits in each of the circles???
how were u able to draw original state diagram is there any logic
even i have the same doubt
Sir,Why have u chosen only the o/ps of same state and not the other o/ps i.e the o/ps of changing the states?
whats the logic behind the state diagram (the first state diagram) is it in a random manner or???
if there are two different outputs for x=0 and x=1 then which one you will put in the circle
same doubt i also have ...if you have cleared your doubt then pls comment
Can u please tell me how the calculation done while drawing state diagram
Original state diagram is fix or something like that? Is there any logic about it or just a memorizing stuff? I am confused a little.
sir can you help me with finding the original state diagram please
Sir, Below I read in one of your comments that you will be replacing this video. Can you please tell if this is replaced already?
@ Neso Academy ..but sir input is 0 and 1 and you show output inside the circle only for one input what happen for other input ?
BUT WE WRITING INPUT IN STATE DIAGRAM OF THE MOORE CKT ALSO SO WHAT DIFFERENCE IN MELAY AND MOORE
Sir how you draw that four circles i didnt get that point
Y=Qa+Qb
u said Y is not a function of input so it's Moore but Qa is function of A(input) as well as Qb? explain.
TH-cam needs a 3x feature.
To Say the clear video for how to moore diagram input and output came
thanks
please sir ,, take the one lecture on vending machine
What a great explanation, Thank you so muh
How to draw a state diagram?
thank you :)
How to draw the state diag w/o knowing the values ,
The one which u drawn first like hw can i come to that( i/p is 0 and o/p 1 )ex
nice videos
Sir please ans. Me
Hoe to find state diagram for Moore state mashine and mealy state mashine?
(It means ki Moore mashine or mealy state mashine circuit diagram par se state daigram kaise nikale?)
How we have to assume input is 1 or 0 ,output is 0 or 1 like this
sir in your moore description state (00/1) and (01/0) are missing.
I think he created it randomly, even though, that case can be given. Some cases may not happen never, in function of the buttons or the circuit, so you might want to avoid showing them in the moore state diagram.
by any chance you have a lecture of state machine in VHDl ?
hello sir.. I have a doubt. does that state diagram belongs to the t ff circuit in the question?
How do we represent a case where different inputs facilitate different outputs in the state diagram corresponding to moore?
***** pls answer this , i got confused too
+Rajshaker Kankula
Keep in mind that in a Moore Circuit the output only changes with the state and is not dependent on the input, which is represented in the information loss.
+Rajshaker Kankula I'm pretty sure it depends if the state diagram can be converted to a moore state diagram, i.e if the circuit is a moore state machine its state diagram should be able to be converted... hope that helps :)
thanks to you
what about the other output?
What is the intro music?
i didn't understand why from 00 il will became 11 with 1,0 like input and output. may you explain?
you didn't show that Qa is independent from A to state that the output is independent of the input A!
i don't understand the state diagram from 6:41 , how to become that input/output ?? . okay i understand now, i have been watch the state diagram video in "Analysis of Clocked Sequential Circuits (with T Flip Flop)" , but what is the purpose of state diagram, what use of that ? thank you
how both the state diagrams have the same no.of states
+Neso Academy
Will Moore state diagram contain four states only ?
When present state is "01" and input is 1 it should give output 1 but Moore diagram goes to 00 which gives output 0 ?
no for the PS "01"the output is written in the bubble that is "1". and the rest is same as it is.
It depends on the sequence ckt diagram..besed on the diagram output will change
In this sequential circuit there is 2 t flipflops that is the reason for taking 4 states(00,01,10,11)
State diagram is drawn according the 2 t ff
Need clarity on original state diagram. It was not clear how it was created
didn't get anything how you convert mealy to moore state diagram??
In Y=Qb' + Qa equation, why Qa is not considered?
kumud tripathi hi
give some more examples on conversion of normal stata diagram to moore diagram
i want some real life based question solution on mealy and moore.
sir how u drawn the original state diagram??
very good!
I feel ur too fast in this video sir
In original state machine which way outputs came
I didn't understand the state diagram
Shahid Raza koi baat nhi...exam m chodh dena aayega toh
SIR CAN U PLEASE SHOW AN EXAMPLE TAKING THREE VARIABLES
Sir yr state diagram is wrong. If you are designing mealy then it will take one less state than u used. If u are designing with Moore than last two output will be 1 and all other 0. If u have any doubt u may write in comment section
Can you Please Explain/Share me a Link of Moore circuit Diagram By using J-k Flipfolp
i didint undersant about the outputs and imputs in the moore?? how can ı dot...because ı only see 1 and 0 and somethimes chance for 0,sometimes for 1
+Sumeya Yenıza Ismael Actually he is not using any kind of logic while calculating output. He has chosen inputs and outputs randomly.
how we make original state diagram
Your topics are all well explained but vedioes is too long to understand... 🙄
Thats your problem
sir plz change the starting music it pushing me into sleep , remaining are nice to see
nice good video
God for ece students
how to write a state diagram and have s little bit confusion
Thanks this vd is useful
sir i need explanation for asynchronous sequential circuits :'[ .. ive my sem exam tomorrow. pls save me from failing. ive been watching your videos for like straight 12 hrs.. just asynchronous sequential circuit is left
Lol
Im not understand state diagram explain clearly
The Moore state machine should have one more state than the mealy
It's not too much clear especially in stating diagram
I dnt understand state diagram
☺Ton of Thanks
