Let x(t) be a deterministic continuous time signal with finite energy. Let X(f) be the Fourier transform of x(t) and let (f) be its energy spectral density. Then
We have f(t) | dt = ₂(f)df
We have Iz(f) = X(ƒ)|
None of the above proposition is right
We have Iz(f) = X(ƒ)|²
Iz (f) is maximum at the origin (that is : Vf, |Iz (f) |≤ Tz (0))
