Time-Invariant and Time-Variant Systems (Solved Problems) | Part 1

[@aritraray3087]

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

1. TV because of time scaling 2. TV because of time dependent coefficient 3. TV because logt is time dependent function

Many professors are watched this video to teach thier students . really this Chanel 👌👌👌👌

[@walidtrex]

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.

All the three systems in Home work problems are "Time Variant Systems"

[@fahadashrafofficial]

you are a great teacher

[@myonlynick]

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?

[@samarthjain2162]

yup

[@arsalanwasim4177]

correct

[@hritikroushan6068]

[@nihadabbikar5788]

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.....

[@naseralbadareen3527]

i think you will have (t-t.)^3 in y shift and (t^3-t.) in input shift , thats why

[@SuperENGLAND92]

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.

[@reasoningbydk786]

[@rifatbinsultan5184]

massive respect - Bangladesh

[@kaushalgarg4014]

Sir,why y(t^3)=X(t) is TVs?

[@Dhruba99]

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)

[@meeras2165]

Thanks ur saving my life

[@sushmanaik2228]

Home work 1.Time variant 2.Time variant 3.Time variant

[@khairulfahim]

y(t)=x(logt) is time varying because input x(logt) is scaled 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

[@happyhuman9625]

Log is not time scaled.Log is just an operation sir.

[@shan_singh]

7:15 why it is time variant ?? why are we considering coefficients unlike the previous cases in finding causal and non causal ?????

[@arthia2801]

You are such aaa wonderful man...tq u man for all your lectures

[@rationalthinker9612]

How does time-reversal work? Say the signal is y(t) = (2-t). Is this TIV or TV?

[@robert_redd1528]

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?

[@charlesrivero9963]

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.

[@TopEgel]

At example 5 / why you change t in cost it is a coefficient ?

[@mohanmurari6889]

At 5:02 ex no 3 I didn't understand how it would be TV

y(t) = cost is an time variant system sir?

[@kurasingarapusatwik]

How y(t*t*t) = x(t) is a time variant system

[@umareddy6197]

y(t)=x(t) => shift in I/P x(t-to) = y((t-to)³)---------(a) =>shift in O/P y(t³-to) = x(t-to) x(t-to) = y(t³-to)------------(b) Hence, from (a) and (b) The system is TV system. Because it is providing an output, which is not constantly varying.
