Unformatted text preview: 5.5 The z-transform of a right-sided sequence h [ n ] is given by H ( z ) = z + 1.7 ( z + 0.3)( z ± 0.5) . Find its inverse z-transform h [ n ] via the partial-fraction expansion approach. Verify the partial-fraction expansion using MATLAB. 5.6 Problem 6.41, Part (a) of Text, Page 349. 5.7 Problem 6.51 of Text, Page 350. 5.8 Problem M6.1, Part (b) of Text, Page 351....
