After searching the entire TH-cam to do my assignment than I found this video. I must admit that your video has help me a lot understanding this topic. Kudos to you.
I don't know a single thing in signal and system ...but after seeing ur videos I can easily understand...Thank u...sir.....really thank u...This is the clear explanation I have ever seen...🙏🙏🙏thank u...so so much sir...
bro... i hope you are very happy with your life and i hope you get everything you ever want. If university professors explained stuff like this, we wouldnt be this stressed. stay blessed! and thank you!
one more type in continuous or discrete for multiple input and multiple output example:- y(t+3) +y(t-1)=x(t+2) +x(t-4). causal Or non-causal. Thanks for help ,very useful. if possible please bring different types of problem for each topic .
Thanks for quick reply, now as per example | understood we should consider y(t+3) first then y(t-1) and check whether input x(t+2) + x(t-4) satisfies causality condition or not , if any one case fails then we consider it non- causal . Am | correct , please reply..
Say we had: (d^3/dt^3)*(y(t)) + (t^2)*(dy(t)/dt) + 9y(t) = dx(t)/dt - 8x(t).... Wouldn't this be non-causal? I plugged in '0' to the system and get present. Then '1....n' gets future. Is this correct?
SIR i have a little bit cofusion... in the examples where we get only present condition ....... instead of putting psitive x value we put negative x values just like x=-1 then we didnt get the same answer ...soo plzz explain it sir
sir you said in the last example that you should apply three values(positive, negative, 0), but why didn’t you apply t=-1 in this question y(t)=x(2t)...you just apply t=0 and then after that t=1...we could put t=-1 and then the answer would be causal..Please help.
Sir kindly explain : In X(-t) you checked for ( t=0, +ve, -ve ) values... while in X(2t) you only checked for ( t=0, +ve ) values if here take t= -ve then it will also give past values .. and will contain all states?
waresha khan Whenever we get future value it is fixed that ans is non causal... We can do all states as well as you said but ans is still Non-causal because of future value
Dear, the point is that causality must be satisfied for all times. Due to this reason, the above system is non causal. If you like the answer, please watch the following video and subscribe our channel. th-cam.com/video/RpAC2gp26Ag/w-d-xo.html
Y(t) = x(t/2) is it causal or non causal .for -ve value y(t) depends on future value but for +ve ,y(t) depends on future value ,so is it casual or non causal? according to your concept it is non causal but the correct answer is causal.explain please
It is linear and noncausal due to x(-n) term. If you like the answer, please watch the following video and subscribe our channel. th-cam.com/video/RpAC2gp26Ag/w-d-xo.html

Ishmam Mahmood y(-2)&x(-2) y(2)&x(2) no delay or adv like y(2)&x(-2) which were present in all equtn except this y(t)=tx(t) future means: y(2)&x(4) present means:y(2)&x(2)
Sometimes I just stare at my professors when I get lost and they prob think wow I'm getting through! He's listening so intently! When really I'm thinking why are you trying to so intently be as abstract as possible?
Jonny I made this video so that you can pass your academic papers easily ... Talking about practical knowledge their exist many videos which are not abstract , so giving same videos like them doesn't make sense
I'm sorry I don't quite understand. I was simply trying to give you a compliment. I study at a nice university but professors like to make things complicated and I love how your video made it SIMPLE to understand this particular topic. I think you're doing a great job, and I hope to see more!

wil do brother
a perfect man. hats off u sir
in example y(t)=x(2t), if we check for -1 we get causal, explain plz.
Present +past + future
Non causal system trick is any one future is there its a non causal dont think about next😊
really ur video is very helpful for me I can easily understand what is actual meaning of this system thank u nd make more this type of video's😊😊😊😍
y(t) = x(t/2)
Please explain this question as well.
As it should be causal but the answer is non causal.
Thanks, you solved out my problem
bro your explanation is superb which textbook did you follow?
At 5:13 if we take t=(-1) , then the equation would be like y(-1)=x(-2) therefore it would be causal since we get the past value. Right?
That is also present value...
Very much helpful as well as clear.

one more type in continuous or discrete for multiple input and multiple output
example:- y(t+3) +y(t-1)=x(t+2) +x(t-4).
causal Or non-causal. Thanks for help ,very useful. if possible please bring different types of problem for each topic .
+ANAND CHITCHAT
You can watch playlist for more topics 😇.
The example you mentioned is Non causal system
Thanks for quick reply, now as per example | understood we should consider y(t+3) first then y(t-1) and check whether input x(t+2) + x(t-4) satisfies causality condition or not , if any one case fails then we consider it non- causal . Am | correct , please reply..
+ANAND CHITCHAT
Check relationship between output and input..
At t= some value..
Where is input ( past , present or future) with respect to output
Thanks for explanation :)
if the system is only in past then is it causal or non causal
like y(t)=ax(t-b)
causal. The system fails the causal test if it depends on the future: y(t)=ax(t+b)
Sir I have one doubt if -1 is present then -0 is future or past???
Good concepts sir , thanks for a help u
Thank you very very much sir 😊
now I cleared all doubt... thanks.

This video helped me in my exams
Thanks ❤️
Very well explained.
Thank you soooo much
At 6:09, what if we did y(-1), wouldn't that make x(-2) and rely on past present and future?
Andre Arson
yes it would take past value
but then it satisfies all states
past present and future ,hence it is NON CAUSAL
Ahh I see. It's like you mentioned in the ending. If a future input value satisfies, then overall its non causal...
Andre Arson
yeah ur r8 😉
Say we had:
(d^3/dt^3)*(y(t)) + (t^2)*(dy(t)/dt) + 9y(t) = dx(t)/dt - 8x(t)....
Wouldn't this be non-causal? I plugged in '0' to the system and get present. Then '1....n' gets future. Is this correct?
Andre Arson
yes
NON CAUSAL
Thank you sir❤
Bhai apne bus simple example but if fiction integration me to kya karege ?
SIR i have a little bit cofusion...
in the examples where we get only present condition .......
instead of putting psitive x value we put negative x values just like x=-1 then we didnt get the
same answer ...soo plzz explain it sir
you put any value
like positive 1,2,3,4
or negative -1,-2,-3
or 0
it remains PRESENT state only
please give examples related to
delta function.
So glad I found this. Thanks!
welcome :)
sir you said in the last example that you should apply three values(positive, negative, 0), but why didn’t you apply t=-1 in this question y(t)=x(2t)...you just apply t=0 and then after that t=1...we could put t=-1 and then the answer would be causal..Please help.
Sir kindly explain : In X(-t) you checked for ( t=0, +ve, -ve ) values... while in X(2t) you only checked for ( t=0, +ve ) values if here take t= -ve then it will also give past values .. and will contain all states?
waresha khan
Whenever we get future value it is fixed that ans is non causal...
We can do all states as well as you said but ans is still Non-causal because of future value
Thank You so much Sir for clearing it,,, Now I got the point..
waresha khan
Welcome 😃
Thanks man ...very nicely explained
what about trig functions, e, log, rect, tri, sawtooth?
+Moises Navarro
They can be solved using same logic 😃
Bro what if the system contains all only past values ??
easy and good explanation...thanks ...

If the equation is x(t) = x(2t) if you put t = -1 then you get x(-1) = x(-2) isnt that present and past? so wouldnt it be causal?
Tqsm... For making it soo easy
at 8:02 i thought t= 2 , y(2)= 2x(2) = 4 , which becomes future. not present. please explain
please explain. i really love your videos. every video i watch from you. i always click like
2x(2) is not 4
thanks for the help man this saved me!

y(t) = x(t) + u(t+1) is causal or non causal
what if y(n)=x(-n)?
when n=1, is depend on the past but when n =-1, is depend on the further.

Y(t) = x(t/2) is it causal or non causal .for -ve value y(t) depends on future value but for +ve ,y(t) depends on future value ,so is it casual or non causal? according to your concept it is non causal but the correct answer is causal.explain please
correct answer is NON CAUSAL...
You have studied r8 :)
Thank you so much for explaining. I have a doubt
Why didn't you take negative value for t in:
y(t) = x(2t)
?????
You can take
But since you get case of future
Ans is non causal
how to do for discrete signals?
Same steps
if i take t=-1then we get y(t) = x(2t) is causal if take t= 1 then it'll non causal
The system y(n)=x(n)+x(-n) is .................. system
Linear causal
Nonlinear causal
Linear noncausal
Nonlinear noncausal
It is linear and noncausal due to x(-n) term. If you like the answer, please watch the following video and subscribe our channel.

i gave like for the animation in the first span of this video :D
y(t)=2x(t)+3
It's a causal or non-causal !!!!
If it is past and future...then system is what ❓
Can we put t=-1 ( even though it's practicallly impossible) for x(2t)
+Cherukumudi Saisrividhya
Yes we can...
But once condition comes future
Other condtn doesn't matters ....
AMAZING!!!!!

one question however, why is when t=1 or t=2, tx(t) is present and not future? Aren't future values those moving to the right of the x axis?
Ishmam Mahmood
y(-2)&x(-2)
y(2)&x(2)
no delay or adv like y(2)&x(-2)
which were present in all equtn except this y(t)=tx(t)
future means: y(2)&x(4)
present means:y(2)&x(2)
So much clearer! Sharing with all my friends for sure! Thank you!
