Checked 50 videos but this is the first video that cleared everything

[@tceterex]

Thanks for taking the fear out of me towards signals and systems

[@shahzebjan9629]

u r abeyond great,,,i in love with signals and systems subject bcz of u

[@ShrenikJain]

Shahzeb Jan your appreciation means alot 😃 share with your friends too 😊😊

[@shahzebjan9629]

sure :)

[@udigal3539]

Very helpful, thank you. Helped me get back on track for working on Space invariant systems

[@praveenpallagani1277]

You are the best choice of me to think of signals and systems

[@andrearson2748]

Please make more videos! I love that you give so much examples and make things simple!

[@ShrenikJain]

Andre Arson you can comment the topic that you find is difficult , so that if I know I can try to make video on it :)

[@andrearson2748]

Do you think you can make videos on checking if a system is Causal/Non Causal, or if a system is Bounded Input/Bounded Output stable? I really think those would make great topics to cover! :) Thank you!

[@ShrenikJain]

Andre Arson I made the video on them but it is in Hindi . link: kzbin.info/www/bejne/gmKcoWyHlsSKosk

[@andrearson2748]

Oh I don't understand Hindi :( I have a question for you... If we're given a function like: Y'''(t) + (t^2)*(Y'(t)) + 9Y(t) = X'(t) - 8X(t) And to check to see if it is linear, would this make it nonlinear because it is multiplied by t^2, and also make it not time invariant?

[@ShrenikJain]

Andre Arson it is time variant because of t^2 it is linear because if you follow my steps the video in hindi . you I'll get it. watch video and note down steps for linear and nonlinear system you I'll get it

[@mr.praveersaxena2469]

NICE WAY TO MAKE THINGS EASIER... GREAT JOB

[@ShrenikJain]

Mr. Praveer Saxena thanks 😁😀

[@hariharanm2906]

very easy to understand

Ty 😃

[@sagarmeena318]

Really helpful bro i was confused but seeing your videos i feel this easy now thx brother.

[@Abhishekyadav-hc5ex]

ye kon mhan bidwan log hai jo unlike krte hai un salo ko jln h kya bhai ne bahut mst concept diya h good bhai

[@ankurrajsinger8558]

sir bahut achha concept clear ho jata hai

[@ShrenikJain]

guruankur kumar Stay tuned .. Next video is on MCQ / GATE questions on this topic 😃

[@j.sawyer4946]

Thank you. This is much more clear now.

[@ShrenikJain]

+J. Sawyer Welcome 😃

[@jahidulislamrakib5953]

thank u sir❤❤.it is very easy procedure for checking time invariant and time variant system

[@ritwikbanerjee8633]

Thanks a lot, very clearly explained

[@ayushsoni8509]

Really very helpful before exams

[@gaolee6132]

Thanks for the clarification. The various examples are helpful.

[@ShrenikJain]

+gao Lee Welcome 😃 Share videos and help your friends too 🙂😃

[@rishadhossain1173]

Fantastic video sir...💯💯💯💯💯

[@sethyy12]

You are incorrect for number 3 of your first set of examples. y(n-1) DOES CHANGE. So it is Time Invarient

[@tceterex]

Great vid. Pls make a simple video on invertible and non-invertible

[@ShrenikJain]

i had made video on it - kzbin.info/www/bejne/jGOTfaCCesh7oqc&list=PLfP-D1tg0DI1VEDhEOVNHrTs_pzt684ou

[@samisonitupou9180]

Thanks man, you are a lifsaver

[@kasyapdharanikota8570]

you explained the topic so easily thank you very much

[@ShrenikJain]

ANY DOUBT ? ASK ON FB page . facebook link : facebook.com/studysimplified/ quora link : www.quora.com/profile/Shrenik-Jain-51

[@manikanta-wr1ui]

What about only dy/dt is timevariant or time invariant

[@spandan1601]

can you explain if y(t) = integral of X(t) with limits( - infinity to t) is time variant or invariant??

[@thrinathsunny2945]

SPANDAN SINHA have u got answer for this if yes explain !!!

[@nurfikhira3584]

Reallyy beneficial. Omg i understood well thank you sooo much

[@ShrenikJain]

[@iolanda5707]

Thank you! You just helped do my homework. Very useful examples and easy to understand.

[@crios9772]

Well explained. Thank you so much.

[@ramathumuluri1053]

If System is time invariant should it be delay or replace?

[@apoorvpandey5058]

Bro what a nice explanation

[@somendutta182]

have u made any video of system stability and unstability?? if u have then send me link ....it will me a lot...thanks

[@ShrenikJain]

somen dutta You can get notes of Video. Fill form to get notes. Stable/ unstable topic is their in this video: kzbin.info/www/bejne/gmKcoWyHlsSKosk

[@aym_97]

Can you please solve the examples in detail like the first example, it would help a lot to understand this topic much better. "hope you read my comment" Thank you.

[@shashankpandey1966]

Great work sir

[@akashranjan7663]

Thanks a lot sir

[@divyakatariya7960]

Clearly explained👍😊

[@udyogam_goals]

sir in problem x(t)-3u(t) why you not applied delay to step input

[@AmitCodes]

Becoz delay is applied only to x(n) only, not to u or cos or y functions

[@sarathsaipeteti6029]

U saved me I love ur videos so much why dont I find u in my 2nd year damn it!!

[@rafihaq3485]

Nice work bro. Keep it up.

[@ShrenikJain]

alone boy ty 😄😄 share with your friends too 😊😊

[@ussefdesouky]

so what i understood that systems are classified into: 1)linear-time-invariant, 2)linear-time-variant, 3)non-linear-time-invariant & 4)non-linear-time-variant is that right? could any one answer me!!!

[@nayankarmakarofficial6294]

thnq sir

[@RLDacademyGATEeceAndAdvanced]

Nice video. However, you may check the answer of 3rd example, i.e., y(n)=2x(n)-y(n-1).

[@nikhilvangari1164]

Yes it's time invarient...He did wrong there

[@RLDacademyGATEeceAndAdvanced]

Fine. Are you a student now?@@nikhilvangari1164

[@electromechanicalmechatron1830]

in your first example ( x(t) -3*u(t) ) why the delay only effects the x(t) ??

[@ShrenikJain]

x(t) is input and u(t) is not

[@electromechanicalmechatron1830]

but u(t) can be a state . usually we use notation x for state and u for input. but anyways , if i have y(t) = C*x(t) + D*u(t) where y is output, x is state , u is input .and applied your method it will give me a time variant while it is time invariant.

[@ShrenikJain]

ElectroMechanical Mechatronics VUB/ULB U(t) r(t) Delta(t) are not changed in delay step

[@rajubjc6349]

Bro..I want proof...of differential equations you spoke of..You directly stated that if there is no 't' as coeffecient then it is TI..

[@ramathumuluri1053]

Legend = Shreinik

[@KANTSHRIVASTAVA]

So much thanks sir

[@myonlynick]

3:40 are you sure that it is D: x(2n-k)? I think it is D: x(2n-2k), because we delay n by k. n becomes n-k. No offence intended.

[@ShrenikJain]

Delay means only subtract k Hence, x(2n-k) is right :)

[@amankispotta5329]

Thanks 🙏😊

[@abhitapole9406]

x(2n) is time invariant system. delay y(n,k)=x(2(n-k)) replace y(n-k)=x(2(n-k)) both will be same

[@MuhammadZeeshan-yg3ky]

No, this is not the case. watch my video to see the explanation and don't forget to subscribe my channel. kzbin.info/www/bejne/aKLaaoh4etmsqrs

Solution of y(-1)=1 ??

[@ayushiranjan5937]

You are far better than my professor ... Thanks alot man😘

[@hunainaghai3342]

What's the solution?

[@hriday3796]

Example no 3 is time invariant but you mistakenly wrote time varient
