@@hambadlengebiharekdin Second one is obv non-causal. Take any input, no matter what the input is, the summation will always give values from negative infinity to infinity. so If you have the number 3 for example as your input, the summation will give values greater than 3 for k, which is obv non-causal.
See casual or non casual systems don't belong on values or amplitude. They only belong on the time(future,past or present) relatively to the output-n .so ,please check answer for second 1 it is casual
In homework problem 2,how is the output is depending on input with respect to time? I think we can not comment on causality unless we know this. Please reply sir..
All are non causal systems. In problem 2, in the entire summation u get like this, y[n]=.........+x[-n]+......+x[n]+......, Now if u consider n=0,u get only present values only. If u consider n=1, u get,y[1]=.........+x[-1]+......+x[1]+......, which is a combination of past and present values. If u consider n=-1, u get ,y[-1]=.........+x[1]+......+x[-1]+....., which is a combination of present and future values. Hence problem 2 is also Non Causal
David the present value is -1 and the past value is -2. Think in this way, the value of x[-2] is already stored in the system, you are just retrieving it by using x[-1]
Sir I was just requesting you,,, if this slides are present in your database please make as a pdf in give me the link in the last video of signals and systems (slides means that you are explaining in the about video sir)
In discrete time, an impulse signal is typically considered causal because it occurs at a specific moment and has a non-zero value only at that moment. A causal signal means that its output depends only on past and present inputs, not future inputs.
causal system- output is independent of future values of input and OUTPUT at any instant..... Non causal system- output depends on future values of input and OUTPUT at any instant...
Aapke behtarin concept ki wajah se main Dtft aur dft sikh paya.
Thank u sir.... always..
Hw problem
1. Non-Causal System.
2. Non-Causal System.
3. Non-Causal System.
indian lecturers you are the best
1,2,3-non causal
1. Non- Causal
2. Causal (Because on the RHS, there is no dependent variable 'n' present. All are constant)
3. Non-causal
1)non-causal....2)non-causal...............3)non-causal.....is my answer is crt?if not correct with explanation
u r wrong dear....

ur right..all 3are non causal..

1 nd 2:- NC
3:- Causal having only past vales of i/p
In homework problem 2,how is the output is depending on input with respect to time? I think we can not comment on causality unless we know this. Please reply sir..
it covers infinity region ,that means all input terms so it is non causal

yes, the system in independent of the independent variable n.

i) Non causal system, ii) causal system, iii) Non causal system
Doesnt make sense, Why the second one is causal system?
Sir I was just requesting you,,, if this slides are present in your database please make as a pdf in give me the link in the last video of signals and systems (slides means that you are explaining in the about video sir)
It will help to to revise any time with PDF
sir, HW problem page of SS and AE is not accessible !! sir plz make it accessible...ty
question number 4 is non causal for all values of 'n'.(i.e nis +ve,-ve and 0)
Sir , will impulse signal be a causal or non-causal?please reply.
In discrete time, an impulse signal is typically considered causal because it occurs at a specific moment and has a non-zero value only at that moment. A causal signal means that its output depends only on past and present inputs, not future inputs.
sir, you are good at the theory part, but the practical part is missing. So please I am requesting you to explain some practical examples with theory
All three are non causal
Can someone please explain the 2nd qn from Homework?. Thank you
Bro put n=2
causal system- output is independent of future values of input and OUTPUT at any instant.....
Non causal system- output depends on future values of input and OUTPUT at any instant...
all 3 are NCS
If the equation is y(n) = x(n) + x(-n);
Is it non-causal and non-linear?
How many of you made this question in mind?
All are non causal systems
Non causal, causal, non causal
all are NC
H.w me second vala problem nahi ho pa raha ha...help sir
How 3rd qus is non causal?
Substitute n=-1 u will get future values, then it is a non causal
All 3 of them are non causal system.
H/w
(1.,2.)nonCausal
I think 🤔 3 as CåuSal
What do you say public 😀
just put n=-1 in the 3rd question you'll see its non causal
1-nc 2-cs 3-cs
NC, CS, NC system
all are non causal dts
All are nc
Both are non causal
non
causal
causal
sir your definition of casual & non definition are wrong . plz clear it sir |
All 3 are non casual systems
all the three system are non causal !
Non causal, causal, non causal
how causal?
