EE253, Fall 201 1 Prof. Essam Marouf DSP I ---------------------------------------------------------------------------------------------------------- Homework # 4 To be Completed by Wednesday 10/1 9 /201 1 -------------------------------------------------- ---- All problems are from O&S Ch. 10 ------------------------------------------ 1) 10.7 (Ed. 2), 10.5 (Ed. 3). Repeat your calculations for both the Hanning and Blackman windows and compare results for the three window types. 2) 10.9 (Ed. 2), 10.6 (Ed. 3). Also, determine the window of the shortest length N that would allow resolving the two sinusoids in signal x 3 [ n ] only. Indicate the window type and length N . 3) 10.19 (Ed. 2), 10.20 (Ed. 3)

Use transform length 64 point first, then repeat for 128 point. For the signal x 3 ( n ), design a window function (i.e., select its type and relevant parameters, if any) that should reveal the two distinct spectral peaks while keeping the spectral resolution as fine as possible. Verify your design by plotting | X ( k )| vs k . 2- O&S 10.22 (Ed.2), 10.23 (Ed. 3)....
