this is such a tough topic in my signals class, thank you for going over every single example possible!!

[@geovannyferrera5430]

Cute :)

[@geovannyferrera5430]

@Calvin Calvin 🤔 yeah sure like if I am going to do something. Just let it be 😂. It was a comment that if it is true you can just forget about it.

Trust me guys shirft playback speed to 1.25 👌. Thank me later

[@karuppasamykk7404]

Thank u man!!

I set my playback speed at 1.75

An ideal impulse function is a function that is zero everywhere but at the origin, where it is infinitely high. However, the area of the impulse is finite.

How a impulse function is unbound function?

[@user-jz7vf6hd4m]

Thanks 😊 a lot, you have helped me about this subject signal

[@ahmedzolali2808]

Thanks lady, it was a helpful video to solve my assignment😁

[@sobangaming1881]

nice mam. I understood all problems. Thanks

[@kumarnripendra2666]

In Vth problem, if we put some finite value at place of x(t), y(t) comes as zero and it should not be considered unbounded. So there is some confusion.

[@Wheelie1999]

The definition of the dirac delta function states that when it's argument is equal to zero, it's amplitude is infinite. Therefore it is not bounded for all t and is unstable.

[@xoxnerd]

very clear teaching!!

[@sakthimathi1964]

Thanks mam

[@devkumar9889]

Why u haven't used Impulse response method ?

[@vanisood3140]

How is an impulse function an unbounded function?

[@akshaysachan6029]

Impulse function gives the slope of unit step function so it is zero at all points except at t=0. At t=0, the step function suddenly changes it's value from 0 to 1 so the rate of change is infinite as the change is instantaneous and therefore the impulse function is unbound.

[@sruthitnair3199]

Impulse signal have value only at orgin and that value will be infinity .if it's specified as unit impulse then it's value will be 1

[@sravanigopisetti2179]

y(n)=ne^|x(n)| is stable or not

[@nareshbhatta8207]

Hats off mam. 👏

[@shreyasingh5750]

how impulse function is unbounded signal? Its value is 1 at t=0.

[@neerajpiparia7199]

The value of unit impulse function is 1 at t=0 but the value of impulse is infinity at t=0

[@aksharaviju6624]

@@neerajpiparia7199 you just cleared a major doubt of mine.. Tysm!

[@sibanisasmal6405]

but if we consider cos wt infinite then it will be undefined then it will not be stable in 2 question

[@prakharn11]

Ma'am plz explain why Impulse signal is Unbounded.

[@sowmiyar1547]

How impulse function is unbounded signal??

[@tusharsharma-jq6hx]

at n=0 the output shoots up to infinity, thereby making it unbounded.

[@shreyasingh5750]

@@tusharsharma-jq6hx as show in just previous video, at t=0 impulse function has value=1.

[@himanshuverma2586]

@@shreyasingh5750 we are just taking the amp of impulse as unity

Plz explain me ,how we get 4 in the last prblm, that is while explaining discrete function in graph u say 4 why???

[@MarinikiPnevmatikou]

Because they get added from 0 and on.

Thank you mam

[@mandarpatil1930]

Why impulse signal is unbounded signal?

[@MuhammadZeeshan-yg3ky]

Because it can be approximated by a rectangle with infinitesimally small width and infinite height. Dear, the point is that causality must be satisfied for all times. Due to this reason, the above system is non causal. If you like the answer, please watch the following video and subscribe our channel. kzbin.info/www/bejne/iKGkdGWdpZdpd8k
