Thank you for the correction @11:04 I was starting to feel like I need to relearn K-Maps. I'm impressed by how clear you explain these things. Thank you for sharing.
You're absolutely right - I could have made this video a little more organized and explained the gates better. But I was just doing all these videos for extra credit and never realized how helpful they would be for others! C'est, ce que c'est!
I have a final project and my final exam this week all on this basic principal. Thank you so much for putting this material up on the web. It has cleared everything up for me. You are wonderful.
i just want to say u r best......................!!!!!!!!!!!!!!!!!!!!!!!!!!!!! please helps us in same way. The way u have explained is just the exact way i want just want to say thank u thank u alto
What if you had a 4-bit counter or something with 10 states, for example? That means 4 flip flops, so how would you know to wire the 4 flip flops themselves? And doesn’t this depend on the type of flip flop? What are you using here? D, JK, SR, etc? And how would that choice affect your circuit?
That K-Map is super confusing. It's helpful to number down the Next column 0, 4, 1, 5, 2, 6, 3, 7 to line up with the k-map boxes. How do you know whether to use an and gate or an or gate when making the state equations?
So, the type of flip-flop was never mentioned, but basically we assumed it to be a D-type clocked flip-flop. Suppose the "clock" part is redundant in what I had said. Anyway, do you have a video on how to make a digital clock that would control a DFF?
Very helpful however, i thought the circuit output was the one written with the state in the bubble when using the Moore model...not the input as you say.
Ahh it took me a second but I think I understand the k-maps For the 1st one, the output represents next state Q1 and the kmap can be interpreted by: x is on the y axis (row), Q1 is on the x axis (left most and rightmost columns) and Q2 is on the x axis (inner most 2 columns). All outputs are for next state and then output y To reiterate, I think it looks something like this, although the equations she derive really throw me off (especially the last one). Q1' Q2' Q2 Q1 X' X
She is using Moore State Machine Diagram and then for finding the Eq of the OUTPUT y she used input X in Karnaugh Map which is wrong...........Kindly explain if I m right...........
You are very confusing, plz don't make videos if you can't explain. Why don't you consider Q1+ and Q2+ as the next state and confusing with the present state????
Jae you did what no other corner of the internet could do, thank you so much. You have my eternal gratitude.
You deserve a nobel prize Ms, this was so helpful!! thanks

Watched this vid with no sound cos i was in the library with no earphones...understood everything!!! Thank you so much :)

I've never seen a k-map done like that before but still, *standing ovation*
i just want to say u r best......................!!!!!!!!!!!!!!!!!!!!!!!!!!!!! please helps us in same way. The way u have explained is just the exact way i want just want to say thank u thank u alto
can you help me understand when you derived the k-map from the present state and next state table.
Great vid, just something I found confusing on the first watch was saying output and input interchangebly.
JK, D or SR ?
She is explaining incorrectly @4:00. It is not the output 1 goes to 10, it is if the input of the next state is 1 it goes to 10.
What if you had a 4-bit counter or something with 10 states, for example? That means 4 flip flops, so how would you know to wire the 4 flip flops themselves? And doesn’t this depend on the type of flip flop? What are you using here? D, JK, SR, etc? And how would that choice affect your circuit?

How do you know whether to use an and gate or an or gate when making the state equations?
Pretty sure she uses demorgans rule on the last equation
***** Actually she didn't.She was confused as Q1 and Q2 stay the same (00) and she should have used Q1' and Q2'.
Your are perfect, just the harsh sound during writing on this paper. You awesome.
She is explaining perfectly
So, the type of flip-flop was never mentioned, but basically we assumed it to be a D-type clocked flip-flop. Suppose the "clock" part is redundant in what I had said. Anyway, do you have a video on how to make a digital clock that would control a DFF?
Can you explain why the OR gate output goes as input to the flip-flop?🤔
THank you for sharing your knowledge… this was super helpful!!!!
To this day I still have no clue what kinda flip flop she used in the circuit
You are wonderful
Very helpful however, i thought the circuit output was the one written with the state in the bubble when using the Moore model...not the input as you say.
WOW thank you so much Jessica! I have my test tomorrow and you are such a life saver!
probably the most torturing 15 minutes of my life. that motherfucking pen.
In your example, the output depends only on the Q1 and Q2. How would be the circuit if the output was to depend on Q1, Q2 and input?
u mean input for output for the states transition
Ahh it took me a second but I think I understand the k-maps
For the 1st one, the output represents next state Q1 and the kmap can be interpreted by: x is on the y axis (row), Q1 is on the x axis (left most and rightmost columns) and Q2 is on the x axis (inner most 2 columns).
All outputs are for next state and then output y
To reiterate, I think it looks something like this, although the equations she derive really throw me off (especially the last one).
Q1' Q2' Q2 Q1
X'
X
Thank you Jae! It's really helpful
MAM, How to take output y=1 when taking x=0.first condition
Very nice. You should tutor people!
Please for the love of God make more videos!
Please i don't understand the k-map.she made for looking for the next state
She is using Moore State Machine Diagram and then for finding the Eq of the OUTPUT y she used input X in Karnaugh Map which is wrong...........Kindly explain if I m right...........
You are amazing!! Thank you so much!
Thanx a lot mam! it really helped me..clear my exams😊😊
ah i didnt go to class to figuring this was extremely hard, thank you
nice video, helps a lot!
what kind of kaught is this?
Thank you Jessika :)
awesome explanation!!
you are a beast make more videos plz !!
Excellent explanation! Thks a lot! :)
This Helped a lot!!
Thanks :)
Thanks for doing this video. It really helped.
Thank you! This was very helpful.
what kind of ff are you using? D-ff? what if we need to use other kinds of ff?
why you didn't tried to minimize the states even mentioned it ?
thank you so much ............
life saver!!!!!!!
I second this in both statements...
Tysm!
Thank you so much, very helpful!
very helpful. Thank you
Thanks alot
thanks Q !!! awsm work. and wonna tell you i like the voice :)
👍👍👍👍
i still dont understand how to find Qx , Qy... ffs :S
very helpful
Go girl! It's awesome seeing women in the engineering field!
Equality can only be achieved by telling women they are special for doing something men do all the time, and constantly reminding them of it.
I bet she can also cook
respect wahmen
Boy if that isn't a blatant attempt at spitting some game haha.
you taught me that in 15 min :p awesome
thanku
Great tutorial! Ps. you have a beautiful, friendly voice! Makes me want to keep listening to you! And yeah, you've got pretty hands too. ^_^
thanks for the video :)
...good god....x=input, but you are saying ouputs....?
I've a digital exam in about 2 hours but...
Hey, how you doin?
not transparent video
You're calling the input the output...other than that great tutorial
thnxxx a lot!!! :)
Thanks a lot! and yes good correction :)
Hi! You made a mistake in the 10.00 minute output y= Q1' and Q2' not Q1Q2. Otherwise your video is very good.
She corrected it later.
thanks a lot....my fundamental is strong now
move your left hand....you are blocking!
thanx and nice ring :p
can u explain this from equation Da = x'y =x A, Db = x'B +xA, z=B
plz help to solve this
saud ahmed no
very unclear..
this first and second video ..
they are what kind of flip flops ? you cant say that because you also dont know that
not so much helpful video
I agree, she's doing that authomatically without depper understanding of synchronous logic circuits
If you take a look at my other video I show you how to figure out what type of flip flop you need :)
Jessica Brown which video?
not a very helpful reply, this video is a pretty bad explanation for students including myself.
You are very confusing, plz don't make videos if you can't explain. Why don't you consider Q1+ and Q2+ as the next state and confusing with the present state????
