Xing O 2 W 4 s 7 (1) If your choices are only: a) Rectangular, b) Triangular, and, c) Hanning, which window would you use to minimize "spectral leakage", and why? (2) Calculate the 8-point window that you chose in (1). PLOT a stem plot indicating the heights of the stems numerically. (3) Calculate the windowed sequence, Xw(n), that results form applying your chosen window to the original sequence. PLOT a stem plot indicating the heights of the stems numerically. (4) Finally, calculate the DFT of the windowed sequence. Indicate each of the 8 X(k) as a Cartesian complex number ( a +bj).
