Homework Statement
Solvinf the unit time step equation mathematically.
Homework Equations
x(t) = u(t+1) - 2u(t) + u(t-1)
The Attempt at a Solution
How can i solve this signal mathemtically :( and using plotted signals , i couldn't understand,
here is my approach and I'm not sure it is correct,
i simply wrote the coordiantes of each signal,
u(t+1) = (-1,1)
-2ut = (0,-2)
u(t-1) = (1,1)
and then added them which give answer = '0' :(
is this the way of solving the signals ?
please help
