Lecture 8 | Basic Operations on Signals | Signals & Systems

[@NityanandaHazarika]

Signal and Systems is a topic that I always remain away from it, Never understood on class, books are also looks horrible, but now I can feel that I have understood something, after watching each video on Signal and Systems I get a pleasure of achievement that I can't express. Thanks a lot sir.

Relatable asf🙋

[@sandeepchatterjee4482]

Same here bro

[@singhankush345]

Great sir...pls provide video on Fourier and z transform...all previous videos are very helpful

[@ozaaditya2929]

sir ramp wale example lelo... unme difficulty hoti he,,,,figure se equation kese banaye...plz upload kijiyega....

[@akankshakumari2802]

Thanks a lot sir......now my all concept is clear because of you.And I did that questions correctly ☺️☺️...I am feeling so happy ☺️☺️..... Happy Teacher's Day sir🙏🙏☺️☺️

[@PratikPatel-yk6sz]

Very good explanation, thank you

[@eddyr978]

@26:30 I think that our signal starts from t=3/2 ..bcz when we put (-2t+3)=0 ..it gives t=3/2 Sir plz reply ...it's important...

[@akankshakumari2802]

Sir ne Jaise steps bataye hai waise banao aap...it is so easy👍☺️

[@arunteja549]

only for u(t) you have to see like that..... If the signal is u(t) then it starts at t=3/2 but in example it is not u(t)

[@shreyasts1903]

try doing shifting first then scaling we endup getting different answer, not able to identify y?

[@onemanarmy383]

Very nice method of teaching

[@pavankumarbabu359]

Superb explanation on basic operations on signals by jasuja sir

[@chokopola8664]

sir thnk u so much... watched all ur videos on signals on the playlist and was able to solve questions as well thnk u sir.. sir are there anything more or these are almost enough for scoring 2-5 marks on signals for gate as i was unable to understand signals before and so I left it but now its very easy so plz tell sir are there anything more to come?

[@9677157246]

Really superb sir👍👍👍

[@afreenofficial6538]

thanku sir....and thanks to gateacademy team....these videos are really really.... good thanku so very much ....if possible pls pls make video on z transform and dtft specially for ee ..........plsss....

[@ruchimadaan573]

Thank you so much sir.Questiones solved.Huge Applause For Sujay Sir.

[@ashwinraj9931]

awesome explanation

[@ajaysurya8271]

Thank you sir for this wonderful lecture 😍

[@deepanshugoyal1250]

Sir your shortcut is very good to check

[@jeevanaranindd5793]

Thank you sir your teaching make my preparation more easy

[@Hemantvlog29]

nice explanation sir , u short out my basic problem. thanks a lot sir u and your team

[@dipeshgupta7825]

sir your lectures are very helpful for conceptual point of view I request you to post one video on addition of continuous time signals I faced many difficulties while doing questions from r.k kanodia. so can u pls post one video on that

[@koustavranjanshee7413]

sir u helped me so much....thanks sir....

[@saikatdas6464]

Thanks sir pura samajh geya

[@FirdoUSAcademy4UPSC]

Love you sir aap K lecture bahut hi useful h

[@adilansari-sx8qu]

Thanx sir. It helps me a lot

[@AKLESHKUMAR-dr3vm]

thank you sir your explain is very helpful .

[@udaychhajed8260]

Sir, if we do (t+3) first and then try to do (2t+3) then it would be wrong, right? Because (if we do (t+3) first and then multiply by 2 then we'll have to multiply whole (t+3) by 2, which will give us (2t+6). Please correct me if I am wrong. I think we should follow these steps=> x(2t) then x(-2t) then x(-2t+3) then -3x(-2t+3). Thank you sir for such amazing content.

[@praveenyadav6061]

I think we should 1st convert the signal as - 3 X ( - 2 ( t - 1.5 ) ), and then we should apply Right to left rule as mentioned by sir.. What you say.. ??

[@shreyasts1903]

@@praveenyadav6061 yess i did the same but i am getting a different graph

[@cricketandbasicscience6812]

King of signal and system

[@umeshchandrakotha]

Make a video on power and energy of signals

[@umeshchandrakotha]

sujay jasuja sir ur such a great person..ur teaching Technics r handy..it helps a lot, students like me.. tq so much..

[@adilansari-sx8qu]

sir please make a video on how to found even and odd part using signal construction.

[@praveenyadav6061]

Sir, I think we should 1st convert the signal as - 3 X ( - 2 ( t - 1.5 ) ), and then we should apply Right to left rule as mentioned by you.. Please correct me if I am wrong.

[@BrandedStatusWristwear]

Same query bro.

[@mituhalder3503]

Strongly thank u sir..

[@anilKumar-op8wb]

sir i have a small doubt...inside time expression if we do scaling before performing shifting why dont we get the same signal as we get in right to left conversion u taught. as u said we are dealing mathematical expressions, doesn't the rule of basic mathematic BODMAS apply here. plz explain.... i am little confused

[@richamishra6160]

anil Kumar If u r doing scaling before shifting then u have to divide the visible shift amount by the given scaling factor n u'll get the exact graph...as u get by doing shifting and then scaling( Natural order of operation)

[@eddyr978]

Do u have also doubt @26:30 ...that the graph should be started from t=3/2

[@deepanshugoyal1250]

Plz provide video in convolution and impulse response

[@deepaksharma3862]

Thanks sir U r great sir

[@sankalpish]

sir plz make a video on sampling it's damn confusing and at the same tym very important for gate

[@shubhamrai173]

Thankew sir....plz discus about continues and discrete convolution...

[@shubhamrai173]

sujay jasuja Thankew sir...

[@sunil_kumar_289]

Watch his videos at 1.25x speed .You will like them more.

[@rounakdas2633]

It was a great suggestion bro

[@somyakumari2859]

Yeah,right

I watch at 1.5x 🤣

[@PardeepLabVIEW]

Thanks sir ji

[@kkumar5676]

sir plz make videos on fourier series coefficients...thnku sir

[@akshitgarg4194]

Sir i think apne mistake ki hai humko 26.50 pe -2t pehle krna tha tha phir 3 add krna tha but apne t+3 krdiya phir 2 multiply kiya 2(2)+4=8 But 2(2+4)=12

[@akshitgarg4194]

Pls reply i think i am right

[@lalitbindal7779]

Sir if plot u(-t-1)by this method that is by shifting RHS one unit and then taking reversal I get the different plot from the one I found on Google pls clear my doubt

[@jatingoyal4947]

Sir waveform se equation bnane ka video bna dijiye ek plsss.... Its really required for ramp unit step etc....

[@lalitbindal7779]

sir if i take minus common the resultant signal is different..plz clear it

[@jatingoyal4947]

Sir figure se equation banane ka ek video bna dijiye....

[@clanguageprogrammingtutori163]

hi all, can anyone please tell me that..if we do first scaling then shifting? when I am doing this …. getting different graph Thanks sir for such great vidoes

[@saimanasathrikutam]

Even I got the same doubt

[@akshitgarg4194]

We have to do scaling first not add i think sir had taught us wrong

[@mayank_182k]

You should do scaling first

[@happygujjar3351]

Sir agr t infinite h kisi signal kaa to time scaling kaise kre.... Pls sir explain it also. I am totally confused while doing this.

[@chiranjeevibiradar7518]

Thank you so much sir...

[@Stoicbanda]

U r best

[@mrunupawar4158]

Sir aapne to signal draw kiya tha -3x(-2t+3) . To vo jo -3x hai vo multiply me hai to divide hoga na ?? Aapne multiply kiya hai ???

[@adityamakwana7622]

no changes in the Amplitude axis

thank you.

[@gauravkapure7856]

pls sir provide video for sampling

[@suniln1967]

Love you sir

[@mahamamir9176]

How can time ever be negative?

[@saimrehan9990]

I think he is considering time like other other independent variable i.e space etc

[@mayank_182k]

Sir you did last 2 questions completely wrong we shoud always do scaling first then time shifting. According to your method scaling a shifted signal should yield in multiplication of scaling factor and shifted factor so it shoud be x(-3t+12) not x(-3t-4)

[@saikatmondal2715]

sir -2 common leker kyu nehi kar sakta?
