For those wondering why she took limit 0-T in the power equation. She shouldve taken 0-T in the energy equation. She put the limit as 0-inf in the energy equation which is incorrect. The limit in both the power and energy equation has to be 0-T. In the end since T tends to inf, the value for energy comes infinity and for power comes 0.5.

Thanks for the clear and concise explanation, it was a big help!

[harshvardhansrivastva]

ma'am why did you take the limit of power signal from 0 to T?
please explain

[md.imranali]

Thanks a lot..your teaching capacity is excellent

[kavitathakur]

mam...plz explain...y u take limits 0 to T for calculating power sig.

[nikarisa]

what will be the solution
for Discrete time(unit step sequence)?

[mdsaif]

Why you take limit 0-T in power equation?

[musharrafmalik]

Why u r taking limit in power from 0 to T instead of 0 to infinity…can anyone explain plzzz???

[challaraja]

We want the explanation about signals and sytem program for using matlab ThanQ madam🙏

[mdsaif]

We take limit 0- infinity in power equation.

Holup, she's taking the integral of x^2(t), so... that would basically be u^2(t) but for some reason changed the variable name?

[sriramadarshnidiginti]

I have a doubt that...she took 0 to inf for energy but 0 to T for power signal....Y shoulnt we take 0 to inf for the power signal tooo...as the signal is of infinite duration...Any one please explain?
