Homework Help: Impulse function

  1. Mar 6, 2010 #1
    1. The problem statement, all variables and given/known data
    Hi guys,

    I tried google for it but no avail so i seek for your help. I have a impulse function x[n] = [1 2 3 4] for n= -4 to 0




    3. The attempt at a solution

    what does the 1 2 3 4 inside the bracket mean? at n = -3, there is a amplitude of 2?


    Thank you.

    Yes, that's what I would interpret it as.

    Although on second thought... -4 to 0 is a total of 5 indices. But you have only 4 elements in your brackets.
