impulse function

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.
