University education is now a joke only their evalution scheme I meant examinations are only valid their mode of teaching and sharing knowledge is now out of date in this wonderful Era. Thank God
Good Explanation, sir. But In Time Invariant/Time variant 1. Delay - whenever delay the time we have to put (t+k) Eg. Meeting start at 10am. Suppose it is delay by one hour. Then it is 11am (10+1).
In causal and non causal the third sum x(2t)=y(t) when we put t=-1 ,then is X(-2) it goes past value then it is a causal signal but when you put t=1 then x(2) it will be in future value ,then it is a non causal signal .what will be the answer either causal or non causal
I have the same question. But maybe it is just non causal since he says when 3 states are present, past present and future, it is considered non causal
For your third example for causal/non-causal you use the equation x(2t) then you set t=1 and therefore x(2*1) -> x(2) being a future value, but if t=-1 then x(2t) becomes a past value. So, my question is “is t always a positive interger, which by the first part of the video I would think not?” Would it be clearer to say that the system is neither causal nor non-causal?
In a system for any value if it depends on future value irrespective of whether it depends on past and present value it will be non causal. The only criteria for non causal is their should be dependency on future value.
thanks, i prefer this kind of teaching compared to the one who uses diagram to determine whether it is time invariant or variant...thank you sir...pray for me for my exam this weekend
31:30 i thought this would be Time Invariant, because y[n]+y[n-1] = 2x[n]. If that was not Time invariant, then why is y''(t)+3y'(t) = x'(t)+2x(t) time variant? could you please clarify?
Test the stability of the following transfer function by expanding it causal and non causal way ,which of the filter is stable. H(Z) = 1/(3Z ^ - 1 + 1) Sir can you please solve this problem ,explain the steps please
What about t= -1, -2 this is not present value that you mentioned, It is past value right ?? then it also get past value..then why y(t)=t x X(t) is causal ?
What is the correct answer???? The system y(n)=log{x(n)} is .................. system ? Nonlinear noncausal Nonlinear causal Linear noncausal Linear causal
In the example at 8:52 in which you tell if Only present value then the system is Causal...Isn't it a memoryless system which only depends on present values ???
Brother can u solve one dout.... Is the following equations linear or non linear and how...? 1) y(n)=x*(n) ;where '*'= conjugate 2) y(n) =Re(x(n)) ; where 'Re'=real part
Time variant-invariant system checking lo signals ni delay cheyali kada sir ...mari u(t) is also a signal ,why do we don't delay that signal sir ...pls clarify sir
In 2nd and 3rd questions...can we take t=-1 or -2..???? If we do so we will get past values... Why to specifically take +ve numbers when we fail at t=0?? Can't we take -ve numbers??

Good Explanation, sir. But

1. Delay - whenever delay the time we have to put (t+k)
Eg. Meeting start at 10am. Suppose it is delay by one hour. Then it is 11am (10+1).
I have watched many videos of this topic but iam in confusion but after watching your video my all confusion is clear thank you so much sir 🙏❤
Thanks so much for this video! Everything was explained so clearly and concisely. Thank you
Never found such a kind of tutorial. awesome bro. keep rocking!!
Explained so easily . Will definitely write on my exam . Wish me good luck 🤞

check whether the following signals are static linear , causal and time invariant y(t) = at^2 x(t) + btx( t- 4)

Thank you so much bro my exams are at 2pm just got the concept of this which was troubling me. Thank u 🙏
Super explanation with plucked examples I will rock tommarow's exam for sure ....Thankyou sir😊
Hey
Most of the confusion in a student's mind is caused by bad teachers who do not know the basics themselves.Thank you for doing a great job.
Same problem bro😭😭
Only reading from notes is not teaching
Very simple explanation. Nice to find this channel before exam... Thanks...

each and every topic is very well explained but I didn't get clarity in time/invariant topic so, can u pls upload one more video on this topic!!!
bro you are great...after 2 hour my exam...... really really helpful.......make more and more video...with example solution

Sir concept bilkul clear ho gya
But if we put t=-1 in y(t)= x(2t) then it depends on past value so how it is non causal....it should be causal
if u got any one term as future dependent its non causal but the converse is not true
31:30 i thought this would be Time Invariant, because y[n]+y[n-1] = 2x[n]. If that was not Time invariant, then why is y''(t)+3y'(t) = x'(t)+2x(t) time variant? could you please clarify?

Exam is 2 hr later and this video explained it well
At 05:39 if we put t=-1 then the equation will become y(-1)=x(-2) and x(-2) is past value........So how is it Non-Causal?????????????
True, but that makes it past, present, and future. So it is non-causal. See: 12:35

Love u bhaiya thanks for your explanation 😘
VERY NICE ...SO SIMPLE
At 5:45 if we put t = some negative value then we get the past value. Then present+past =causal system can u please clear this dought
I also have same doubt
@@sowmya9042 if ur dought gets clarified then share it to me.
@@vivek9536 it satisfies 3 cases., so it is non causal
@@sowmya9042 I am not sure about your reason. But it is ok till some extent. And tq for ur time

Regarding the linearity , Linear systems need to satisfy both additivity and homogeneity . You need to checkout your methods.
