Need help with homework

[ArmenK]

Anyone know how to do the inverse of a discrete time fourier transform for X(w) = -2e^(-2wj) where pi/2 < |w| < 3pi/4 ?? A sinc takes care of the magnitude but not the phase so it doesnt work

well, at least you arent asking how to solve quadratic functions.

i have no idea how to help you, sorry.
