Signal Construction Example #2

Join the YouTube channel for membership perks:

We often deal with "simple" signals in a signals-and-systems course that can be easily described as a linear combination of time-shifted unit step and unit ramp functions.

Just as in the previous video, we again are provided a sketch of a "simple" signal x(t) and we develop an equation for x(t) in terms of time-shifted unit step and unit ramp functions.

thank you so much!!! just 1 video and it's worth than my lecture at university. This is what I'm trying to understand for days!!!

Super useful as i'm taking a signal processing course... THANK YOU ADAM!

[larajanelabutong]

I'm watching this for the sake of online class during the pandemic. Thanks!

[ramisaibdita]

You have made this really simple. Thank you!

[blogan]

Thank you! Very concise and informative.

[bhawnadiaries]

please add some more problems on signal construction to clear the concept....this was awesome...but still needs to watch some more to get into d concept...plz

[whoisitidk]

A big thanks for making everything clear!

[annyasaroy]

Explained beautifully... helpful indeed...Thanks!

Sir, how you consider 1 at u(2), because according to your previous video it should be 2 yup.

[omardelacruz]

Say we have a positive ramp function with slope = 1 starting at t=0, then at t=1 the signal falls and commences as a horizontal line from t=1 to t=2. How would you write this when there's two things that happen at t=1?( adding a positive slope to make it horizontal then subtracting a step function??)

How to construct this signal sir i have confusion in it.

[hananalbaloushie]

you said that the ramp function is equal to 0 if t is less than or equal to 0! Is that true? I checked it online and my professor told us that the ramp function is equal to 0 only if t is less than 0. if ramp of 0 is t then the x(t) won't be equal to 1 at t-1.

[aakarshankhanal]

Didn’t understand the checking part. How is u(5) =1?

[johnfox]

Oh god, the train. I'm getting fred Harris war flashbacks.

[Dasnthing]

Don't you have to create a ramp function that cancels the first where the value is held from -1?

[ladybuggaming]

x(t) =(3t+1) (u(t +2)+u(t-2)) how to solve this question? What to do with 3t+1 part?

[essayehfares]

confused how the last one is r(t-2) isn't that 0*r(t-2)

[mahmudulhasan]

thank you so much sir ..but i have badly in need the matlab code of this singal..
please sent the code as soon as possible..
