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.

haan bhai ghur pr bhi sbh badiya. teri yaad ati hai ajkal kafi.

[@Ec360Gaming]

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

[@harshvardhansrivastva4914]

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

[@christopherandelin]

There is no need to integrate from -T to 0 because the unit step is 0 when t < 0.

[@eccesignumrex4482]

You need the average function value over a (any) period. 0 to T works, then the length of that interval is 2T.

Thanks a lot..your teaching capacity is excellent

[@kavitathakur8576]

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

[@sriramadarshnidiginti3291]

@@sumitanand2116 Sir, 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?

[@soudipkundupodder4370]

@@sriramadarshnidiginti3291 because power should be calculated within a time period say T, that's why we add 1/2T in the front

[@nikarisa6148]

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

[@mdsaif2560]

We take limit 0- infinity in power equation.

[@mdsaif2560]

Why you take limit 0-T in power equation?

[@challaraja2560]

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

[@arpitalandge8093]

Thank you mam

[@jyotispatil4134]

Super mam....

[@musharrafmalik755]

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

[@atchumnaidukadagala3140]

Madam y u gave power limits as 0and t

[@TrueDetectivePikachu]

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?

[@TrueDetectivePikachu]

so for example for 3u(t) for example it would be 9x^2(t) for 2u(t-1) it would be 4x^2(t-1) not sure if I'm grasping it right

[@adugnamerga1789]

thank you mom.

[@sarthi127]

She did mistake so we'll take 0 to T in both cases bcz T already tends to infinity

Communications joke: is she signal?
