In this part(d), First I solved the DTFT with respect to n, then I assumed theta to be the new frequency variable and finally applied the IDTFT definition with respect to theta. --[[User:Vchaudha|Vchaudha]] 23:42, 19 April 2009 (UTC)

Anyone have any luck on the last part? I tried expanding out $ W(\theta) $ and $ X(\omega+\theta) $, but that only got me as far as an integral in one variable, and a couple infinite sums in two other variables... --cg49me 22:37, 16 April 2009 (UTC)
