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

@ashishtiwary7947 11 месяцев назад

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

@robert_redd1528 2 года назад

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?

@myonlynick 6 лет назад

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?

@arsalanwasim4177 5 лет назад

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

@harinathvatti4377 5 лет назад

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

@walidtrex 5 лет назад

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.....

@naseralbadareen3527 4 года назад

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

@SuperENGLAND92 3 года назад

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.

Vinay Vinni i guess taking cube roots on both the sides... Which makes the rhs^(1/3)...... Just a random guess

@kaushalgarg4014 3 года назад

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

@Dhruba99 Год назад

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)

@faizulislam1075 6 лет назад

All are TV sys.

@andrewpersaud4144 6 лет назад

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.
