transform
Use the properties of transform and properties to find the DTFT of the following signals:
(a) x[n] = (n - 2)(u[n + 4] - u[n - 5])
(a) x[n] = (1/3) n u[n + 2]
Use the tables of transforms and properties to find the inverse DTFT’s of the following signals.
(a) X (e jw) = j sin(4w) – 2
(b) X(ejw) = e-j(4w+ π/2 ) d/dw [2/(1+1/4 e-j(w-π/4 )) + 2/(1+1/4 e-j(w + π4 ))]

4. Find the z-transform (if it exists) and the corresponding region of convergence for each of the following signals. To the extent possible, use the properties of the z-transform to enable the re-use of standard results and reduce calculations. Simplify your expressions.
