Such a awesome lecture . I remember my Faculty was trying to make us understand this topic and he tried a lot but nothing I understood.. Now jst by seeing the problem I can say about it.. Thank u soo much.. 🤩

y(t)=x(logt) is time varying because input x(logt) is operated by log. y(t)=t^2*x(t) it is also time varying because coefficient is t^2 which is a function of time means varying with time. 3) the added term logt is a function of time also means it is also varying with time so It is also a TV system
Hey hari, Let's re-check the grammar of your sentence. "Many professors..." -ask yourself when are they doing the watching? past? present? future? you used the auxiliary verb "are" with a past verb "watched", and are is used with present continuous, so if you want to use are, it would be, Many professors are watching this video... etc. However in your case it would be much simpler to use the present simple... Many professor "watch" this video to teach their students. Hope this helps in the future.
sir your lectures are very much helping me to understand the concepts in simple manner.....osum teaching sir.....and one more thing sir can u prove how y(t^3)=x(t) is a time variant.....proof sir i am confused trying that.....
Thank you! I was having a hard time understanding the difference between x(t-to) and y(t-to), and now I just feel dumb because you made it seem so obvious.
For quickly determining: System can perform anything but it shouldn't involve t (time variable) in it. More specifically (time scaling, additional term {other than x(t), y(t) and contants} are prohibited)
can someone explain example number five? he said they aren't the same, yet its a time variant system? something about the scaling of cosine but when he solves for x(t-to), cosine also shifts?
ALL given signals are Time Varying First one includes time scaling Second one has coefficient which is time dependent In third one added term is time dependent
my prof tried to fool us with some big complicated equation and asked if its TI or not...Didn't even phase me...just looked for the co-efficient with the t in it, looked for the input and knew right away it was time variant lol.
I think x(t) -> delay t0 -> x(t-t0) -> sys -> x[Cos(t-t0)] and not x(Cost - t0) , plz verify. i.e y is x(Cos of whatever inside bracket of x ) -> x [Cos ( ) ] plz verify.
@@KirkHammer-fj2of past 2 years after this comment but i must ask this. I think you are right but you thanks to neso as reply. I cant see neso's reply. Can you explain which one is true. Your or Neso's ? :)
All the Signals given for H.W. are Time Variant.
Reasson:
1 - Time scaling;
2. - time dependant coefficient;
3 - The added term is time dependant
right
Correct

The best thing is the problem solving. Thanks for these great lectures
Your explanation really helped me to get rid of confusion.Such a wonderful lecture...
all the homework questions are time variant systems. Is that right?
Its been three years of doing it right.

Please correct me if , I am wrong.

Thanks, Sir I understand how to solve the problems on time-invariant and time-variant

Its been seven years of doing it right. Why not a revision .
you are a great teacher
y(t)=x(logt) is time varying because input x(logt) is operated by log.
y(t)=t^2*x(t) it is also time varying because coefficient is t^2 which is a function of time means varying with time.
3) the added term logt is a function of time also means it is also varying with time so It is also a TV system
sir you have earned my respect than our useless faculty💖💥
Sir,, You are so briliant
Many professors are watched this video to teach thier students . really this Chanel 👌👌👌👌

Thank you for your short and easy explanation.
Thank you so much.... Its very useful
Thanks ur saving my life

for 1) y(t) = x(logt) we have: a) y(t-to) = x(log(t-to)) and b) x(t-to) -> system -> y(t-to) = x(logt - to). Thus,system is T, V. IS that proof right?
yup
correct
Yes absolutely correct

sir your lectures are very much helping me to understand the concepts in simple manner.....osum teaching sir.....and one more thing sir can u prove how y(t^3)=x(t) is a time variant.....proof sir i am confused trying that.....
i think you will have (t-t.)^3 in y shift and (t^3-t.) in input shift , thats why
I think you can write y(t)=x(t^1/3) instead of given equation and i have tried some t values on that equation. They're equal and both time variant.
Nice explanation. Thank you
U r great sir !
You are such aaa wonderful man...tq u man for all your lectures
Great lecture
Thank you sir
1. TV because of time scaling
2. TV because of time dependent coefficient
3. TV because logt is time dependent function
Thank you!!
sir please upload power system and control system lecture

thank you sir! it really helps me a lot.
Thak you sir for this nice lecture
How does time-reversal work? Say the signal is y(t) = (2-t). Is this TIV or TV?
It would be really helpful if you provide answers for the homework problems.
Great 👍
All the three systems in Home work problems are "Time Variant Systems"
Thank you! I was having a hard time understanding the difference between x(t-to) and y(t-to), and now I just feel dumb because you made it seem so obvious.
Sir is oppenheim enough for signals and systems(gate preparations)?
Do more problems on other books also
Sir,why y(t^3)=X(t) is TVs?

y(t) = cost is an time variant system sir?
Yes!!
can someone explain example number five? he said they aren't the same, yet its a time variant system? something about the scaling of cosine but when he solves for x(t-to), cosine also shifts?
thank ❤
At example 5 / why you change t in cost it is a coefficient ?
7:15 why it is time variant ??
why are we considering coefficients unlike the previous cases in finding causal and non causal ?????
Can someone explain with steps why example 3 in time variant?? I think it is time Invariant. Please help.
Time scaling
super
Is integration x(t) dt TIV or TV
Explanation
At 5:02 ex no 3 I didn't understand how it would be TV

all the three questions are time variant systems
I didn’t understand why 3rd HOW is TV
1,2,3 all h.w are T.V system
All are TV Systems
how the system is time variant if time scaling is at the output
why is y(t)=x(-t) TV
and x^2(n)?
The answers are as follows :-
(1) Time variant system
(2) Time variant system
(3) Time variant system
Could any one prove 3.y(t^3)=x(t). Is time variant
Vinay Vinni i guess taking cube roots on both the sides... Which makes the rhs^(1/3)...... Just a random guess
