Time Shifting of Continuous-Time Signals 

Was worried when your channel was hacked. Always praying and retweeting your tweet to bring back your channel

I'm a Canadian engineering student, and I found this really well explained. Thanks a lot!

another shortcut trick is .. when both sign are same i,e(t+2) , (t+4) then do left shift . And if sign are opposite ie (t-2), (t-4) then go for right shifting...

took me a while to understand the bomb example, for those interested I'll write down my way of explaining what's happening and pls correct me if I'm wrong: Imagine you're sitting in front of the bomb and you have a timer that started when the bomb was set off. For example, you're at 9:00 minutes now (you've been sitting there watching the bomb for 9 minutes) and for some reason, you now cut the red wire that makes the bomb explode 2 minutes earlier. You can say that the bomb will explode at 12:00 - 2:00..... or you could imagine that you're now 2 minutes forward in time. You're not at 9:00 anymore, but 11:00. 9:00 is the instantaneous time and it now became 11. You only have 1 minute to flee. Neso explained the same thing considering you were at 10:00 and that's the number you see on the bomb cause that thing on the bomb is the timer. There's a 10 in it meaning that it started from 0:00 but now it arrived at 10:00. If no one cuts the red wire it arrives at 12:00 and BOOM, otherwise, it's going to explode right NOW. In fact, NESO says at some point "the bomb will now explode".

Thank you sir...precise explain without wasting of time

Thank you for explaining time shifts rather than just stating the notation as I've seen in many other videos!

thank you so much, interesting subject and illustration

Good Explanation 💯

Thank you for the video.

Thank You!

Summary:- Subtracting a fixed positive quantity from the time variable will shift the signal to the right (delay) by the subtracted quantity, while adding a fixed positive amount to the time variable will shift the signal to the left (advance) by the added quantity.

Time shifting is a little bit counter intuitive topic but your explanation with the example really help me understand it. Thank you..!

i like how time shifting is counter intuitive.

It is so interesting and better if you can increase the sound of the video when editing

Extremely helpful! thank you, Sir! It would be great if you have PDF Notes of your work!

Thanks

its good to have straight A's.

please do make some video on convolution integral of both continuous and discrete time

are you going to make videos on Fourier Series, Fourier Transform? Etc?

THANK YOU SO MUCH

Thank you

i have an exam tomo . thank sir verymuch

a good chanel bro

why is the signal in the case 2 is triangle instead like earlier ones which were square or rectangle?

Sir, your videos are really helpful for me because in the 7th semester we read this course. Your approach to explaining things are extraordinary.

I watched it.

Can you please upload lectures on Fourier series n transform

sir if we subtract 2sec of time from original time.for suppose t-2.it is redusing the original then why we not call it as time advance.

Nice lectures and good way of explaining If voice is louder it's better

Nice

Sir but how are u taking her time in negative domain

Why we can't advanced real time signal...

There is a sudden raise at 0 and 2 u can't directly say lessthanorequalto it is less than in continuos signals

But in my textbook it's written if K is negative that results in left shifting and you said the opposite?

sir can u please explain in more detail why we do left shift when we have +ve value of k

Could Neso come out with a better explanation or suggest any other video which explains this time shifting in a more understandable way ? I am of course aware and appreciate the fact that these videos are available for FREE.

9:53 that's 4(seconds) shifted

in signal and system book by oppenheim on page # 38 ,39 the concept of time shifting is vice versa to your lecture can you please guide clearly

what is the solution if x(t+2) and x(t-2) is to be happened from 2nd quadrant?

why we cannot advance a signal in real time?

X greater than 2 and 0greterthan t lessthan 2 that is explain bro

can you give me some practical applications for time shifting both negative and positive

can u explain advanced signal is not possible? with example, because the audio(songs) can be compress

Sir one doubt if time bomb is set at timer 10 minutes then how it will explode at 12 minutes sir as you told.

What is meant by recorded singal

i think the shifted amount is wrong in both cases by 1 unit

X(2-t)..?

what do you mean by advancing of singnals?

thank u so much , but in case 1 when ''k'' is positive you reflected the signal about the vertical axis did not shifted it to the left by 2 ...

it is very good but we hope you will also prepare according to GATE EXAM EXAMPLE

Your videos are best on RU-vid for signal and system but since there is shortage of time can you please tell most important topics for internship tests so that i can focus on them first as there are lot of burden from other subjects too. Please.

in the first case i understood why u made a left shift for time advancement but I did not understand why u inversed the signal . u did not inverse the signal in the second case for time delay

what is the meaning of advancing the signal.........couldnt understand the last few seconds

work on your sound quality plzz...

How the hell for case 2 it's x(t-2), when we pick -2 as t coordinate and then do subtraction to get y=x(t-2) => x(-2-2) = (0:-4) thus function value x equals to zero at coordinate t = -4 that's a function y values, and here you say it's actualy 0 how the hell does this work when you subtract negative two from negative two and have 0 what the hell is that math.

Why k=2 time is left shifting and k=-2 time is right shifting

content is nice so please take care of voice

IS THIS LECTURE COVERS COMPLETE GATE SYLLABUBS?

lectures is very useful for me if voice is louder it's better fol all viewer

can we prepare for ipu exams also from these lec???

In time shifting with k=+2 , It must be shifted to left, not to reflect it

Iam full confusion in this lecture

sound of the lectures is very low ...please consider the matter

sir time negative kaise ho skta hai?

This time shifting is confusing.

FBI wants your location 3:49 😂

views kam aaye toh lagaye tumne ads thats fact

Not understood

voice is too slow not audible

X(2-t)..?

X(2-t)..?

X(2-t)..?
