Fourier Transform magnitude and phase spectra

scarebyte

1. The problem statement, all variables and given/known data

Graph spectra magnitude and phase of F(w)= e^-iw if Abs(w) < 2Pi; 0 if Abs(w)>2Pi


2. Relevant equations

3. The attempt at a solution

For Magnitude spectra:
Abs(F(w)) = 1 if Abs(w) < 2Pi; 0 if Abs(w)>2Pi <- IS correct?

For phase spectra:
Phi(w)=-w if Abs(w) < 2Pi; (NOT SURE WHAT HERE) if Abs(w)>2Pi

Thanks.
