Homework Help: Compute the Energy of the signal

  1. Jun 5, 2010 #1
    tr(0.1t-3)
    tr(0.2t-3)
    p((t-5)/4)
    compute the energy?


    As far as i know,
    i tried to plot the functions and calculate the area under the triangle. but i am not sure that i find the correct answer. Could you let me be sure about the answers?

    My answers
    1st-->5
    2nd-->2.5
    3rd-->4

    energy of a signal is the integral from negative infinity to positive infinity of the absolute value of the function squared.
