Ive been doing laplace and z-transforms for the past few weeks and have moved on to fourier. I need some help setting a problem i have... honestly im not sure how/where to begin... it seems simpler than i am making it out to be. Can someone give me some advice? Thanks!

The problem is...

Determine the Fourier transform of the function:

f(t)=A for (-T <= t <= 0) and -A for (0, t <= T).
