Here first we need to shift the entire u(n) to right by one sample and then apply time reversal property. The limits will be from minus infinity to -1.

[lingeshkumar]

The limit for unit step summation is wrong it is from -∞ to -1

[amittak]

By applying wrong concept you are getting right answer. Shifting property apply on n. We have to take -1 common then we will left shifting.

[njuman]

shift is actually -(n+1) ≡ -n-1. so it's a left shift... so limits should be from -∞ to -1

[jih]

When you decided to switch the borders, you missed switching the 1 to -1. The new borders are sigms from -1 to infinity

[mdparvejalam]

Phli bar z transform sequence ka topic sahi se samjh me aaya tq mam

[FinixFunny]

is this video part of a playlist? I'm interested in a complete series of this

[naveentechie]

Akka o ni valla four subjects pass ayyam akka o thank for your wonderful videos

[euphoria]

Mam (-u-1 ) in time reversal opposite to the shifting so it is obtained by shifting the reversed signal to left by -1 units hence the limits - infinite to - 1

[waqarmehdi]

Ma'am please rectify your concepts of shifting and scaling of signals.

[Crazy_thoughts]

Here u(-n-1) is folded left shift so limit ranges from -infinity to -1

[harshvadher]

Bhai limits are perfect.
Take +n=k and use u(k-1) you will get.

[ashutoshpuri]

She got right answer by making 2nd mistake....1st mistake was wrong limit and 2nd was she changed limit of -infinity to 1 to 1 to infinity..which was possible only when limit is - infinity to -1....

[ashokbanjara]

This was my biggest problem thanx a lot for this mam

[Amarjeetsingh-vkbn]

What will be the roc of this sequence?

[limnasainudeen]

Its a left shift. So pictorial representation will be zero from n=0 towards the right

[tanzimkakon]

What is the ROC for this (az/1-az)?can anyone plzz tell me?

[tanitoxeolee]

8.02 how do you do cross multiplication?

[yeetedlemonade]

May I ask, what will be it’s ROC? For example if a = 3?
