Unformatted text preview: ENEE 241 02 * HOMEWORK ASSIGNMENT 14 Due Thu 04/09 Let the signal s = bracketleftbig a b c d e f g h bracketrightbig T of Homework Problem 13A have DFT S = bracketleftbig 3 2 4 1 2 1 5 3 bracketrightbig T Without computing any DFTs or inverse DFTs, determine (in numerical form) the DFTs of the signal vectors s (1) through s (7) constructed in that problem. The MATLAB functions OSHIFT , OFLIP and FDIAG found in the Assignment 14 folder can be used for circular shifts, circular reversals and linear phase shifts (by means of F ). You may use these functions to verify your results in MATLAB. Just copy these Mfiles to a local directory and include that directory in the MATLAB path. Solved Examples S 14.1 ( P 3.11 in textbook). The timedomain signal x = bracketleftbig a b c d e f bracketrightbig T has DFT X = bracketleftbig A B C D E F bracketrightbig T Using the given parameters, and defining λ = 1 2 and μ = √ 3 2 for convenience, write out the components of the DFT vector X ( r ) for each of the following time...
