Signals and Systems Lec-4: Operations on Signals

In this lecture, different operations on a continuous time signals are explained with examples.

[fikrattalibli]

Now, this is the only lecture series that legitimately teach you something in SS. Like upcoming videos including given and subscribe from me. This is the real deal.

[hematutorials]

Sure unit step, ramp impulse evi discrete signals kadha sir

[sathasivam_rks]

Ji How can i access the hidden videos ?

[saideepgalipelli]

Sir adjust the camera.. properly.. we cant see the whole page

[sandeepsanat]

Sir could u pls do video lectures on control system, communication system and electromagnetic

[KamalKumar-rtxx]

In the example of shifting and scaling, if I'm doing Ist shifting then reversal the answer should be changed why sir?
X(-(t-2))
Ist shift and then reversal

[gkk]

Sir, if suppose a discrete signal is scaled and if that scaled signal is having amplitude at n=1/2 then should we consider that sample.(As discrete signal exists at only. Integer values)

[dr.a.mohanbabu]

your lecture looks good. I expect more videos. When is your next upload for remaining topics in Signals and systems like Z transform and Laplace transform

[NeerajGupta-epwx]

sir, does this series contains sufficient theory to crack all ques in s&s gate exam?? and which book should i prefer for practice prolems.... i have not enrolled in any coaching..plz rply?

[durgaprasad]

sir rectangle and triangle signals mee dhi problems solve chesi oka video petadi sir kocham confusion ga undhi plz sir

[Surajgehlot]

Sir In x(2-t) Example
x(2-t)= x(-t+2) = x[-(t-2)]
First Step: Reflection x(-t)
Second step :Shifting x[-(t-2)]

But there is difference output if we do scaling first and then reflection
First Step: Shifting x(t-2)
Second step :Reflection x[-(t-2)]

So sir do reflection work on (t-2) or it work on (t) only.

[RajeevSharma-rpzw]

sir please try to upload 2-3 video a day.

[amalnathe.g.]

Thank you sir. It's very useful. But I would like to make a suggestion, please spell the word as 'zero' not 'jero'.

[shrutijaruhar]

Sir add method 2 procedure ie how to do x-(t-2)

[keerthanaravichandranbsnlj]

sir i need more questions on this.i cant find the pdf link in ur blog.please provide me the link.

[quadir]

Sir could you please do video on addition, subtraction and multiplication of sine and cosine signals

[snehaprapurna]

why cant we do x(2t) and then do shifting (x(2t+1)) why did u do x(2(t+1/2))?

[durgaprasad]

rect(t - 2/2) + rect (2t - 3.5) explain cheyandi sir

operation what you have done for x(2t+1) is wrong. we must always scale and then shift.

[birendraprasaddas]

why in case of x(t-2) we are adding 2 is there any specific reason.
