Determine the input { x [ n ] } 8 n =0 that will generate the output sequence: { y [ n ] } ∞ n =0 = { 1 , 2 , 2 . 5 , 3 , 3 , 3 , 2 , 1 , , , , . . . } . Problem 4.4 Find the ztransform, including the region of convergence, for each of the following sequences. 1. x [ n ] = ( 1 7 ) n u [ n ] 2. x [ n ] = ( 1 7 ) n u [n1] 3. x [ n ] = ( 1 7 ) n u [n + 1] 4. x [ n ] = ( 1 7 )  n  2...
