Consider a LTID system that is described by the difference equation y$[$n$]-1/4$y$[$n$-2]=$x$[$n$-1].($a$)$ Use transform $-$domain techniques to determine the zero$-$state response y zsr $[$n$]$ to input x$[$n$]=3$u$[$n$-5].($b$)$ Use transform $-$domain techniques to determine the zero$-$input response yzir$[$n$]$ given yzir$[-2]=$yzir$[-1]=1.$
