Signal Construction Example #2

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.

    No, I'm pretty sure the videos are correct. Can you tell me what time in the video you think there's an error? u(t) is the unit step function and is equal to 1 for all t >=0 and zero otherwise So, u(2) = 1. r(t) is the unit ramp function and is equal to r(t) =tu(t). So, r(t) is equal to t for all t>=0 and zero otherwise. So r(2) = 2*u(2) = 2*1 = 2. Did you maybe mix up the r(t) and u(t)?

    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??)

  • @AdamPanagos

    Yes, what you said sounds perfectly right. If "two things" happen at the same time, just put two signals at that time. You could put a unit step to shift things, and a ramp to change the slope. Hope that helps, Adam

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

  • @AdamPanagos

    @AdamPanagos

    7 жыл бұрын

    That's what the final ramp term r(t-2) does. If the last term was not present, we would continue to decrease with a slope of -1 for all time. Adding in r(t-2) adds a slope of +1 at time t = 2 to cancel it out. So, the final slope at t = 2 is -1+1 = 0. Thus, we hold a constant value for the rest of time. This constant value happens to be zero. Hope that helps.

    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.

    Either definition is the same. You can define it as: r(t) = t for t>=0 and 0 for t Or you can define it as: r(t) = t for t>0 and 0 for t
