im trying to understand how to calcuate a Phase of a function in the frequency domain.
from what i know, to calculating a phase i need to use this formula :
arctan(Im/Re)
now im trying to calculate the phase of this func:
f(w) = e^(-jwT/2)*sinc(w/Ws)
this is FT of shifted Rectangle func.
now from what i see there is no Real part in this func so how do i calculate the phase?
the phase graph of this function is looks like f(w) = -w.
i hope it was clear, thanks!
