Operations on Signals | Example 1

[@mshary8943]

THANKS A LOOOOT you explained it perfectly and easily, i was suffering to understand it

[@EnggClasses]

Most welcome. Meanwhile, subscribe to our channel EnggClasses for more quality videos. kzbin.info

[@GulshanKumar-ls5oe]

Love the way you teach sir, nice content in short video☺️

when the u(t-1), its indicates that t = 1, while when u(t+1), t = -1, assume that t + 1 = 0, use t as the left side and move 1 into the right side. simple algebra.

[@mohammedarif7766]

for 3rd signal and 4th signal how you got -1

[@chrisshanshou387]

thx so much for this lecture

[@vamsikrishuv]

How do you get amplitude 1+ time signal 3=0 how do you write 4th signal as zero

[@حلميمنصورحسنالرحيمي]

excillent for this information and more introduction i wish for you

[@safvanalhuda5096]

Hey appreciate your effort can you do with discrete signal as well

[@EnggClasses]

Thank you Safwan. Yes those videos are also in the pipeline. Do subscribe for more videos.

[@vivekkumarmahto3258]

Thank you very much

[@h0difaem104]

Thank you

[@sameertyagi21]

Awesome bro

[@navyagayathri449]

In 3rd signal it is about amplitude -2 but u made it -1 how come sir

[@kartikpm1290]

4th signal how's you get 0 amplitude please reply

[@mohamaduhadijatu736]

New amplitude at a time=previous amplitude on graph at that time plus amplitude at which switching starts at that time for the new graph.

[@danilocouto7585]

Thank you!

[@jeromepouangamkameni2235]

Perfect

[@mercesletifer6625]

I think the x(t) graph is wrong🙄🙄🙄u took amplitude 1 and -1 instead of 2 and -2

[@mohammadhaider4417]

Thankyou sir

[@HelloWorld-zt4ol]

Is U(-t)= -U(t). Plz reply

[@EnggClasses]

Nope.! In U(-t) time is getting reflected and in -U(t) amplitude is becoming negative. Both are different. Hope this helps.

[@HelloWorld-zt4ol]

Ok. It means in U(-t) line with amplitude 1 is on the left side of x axis . In -U(t)below y axis.

[@EnggClasses]

Exactly.! You got it correct.

[@amaljohnson4008]

3rd signal amplitude was -2 you sketched -1

[@an-py3hl]

❤

[@alinizarabed]

F(t) = t^2[ u (t-1) - u (t-2)]

[@sanjitpaul3944]

Your addition for this signal is not clear..🤧

[@pratheeshpraveer6182]

Fourth signal is wrong...please do check that...

[@EnggClasses]

Thanks for the comment Pratheesh. Yes, I did check again, but there is nothing wrong. Fourth signal is u(t-3), its an unit step signal shifted to the right by 3.
