GATE ECE 2016 Set 1  Question: 8
Consider the sequence $x[n] = a^nu[n] + b^nu[n]$, where $u[n]$ denotes the unitstep sequence and $0<\mid a \mid < \mid b \mid<1$. The region of convergence (ROC) of the $Z$transform of $x[n]$ is $\mid Z \mid > \mid a \mid$ $\mid Z \mid > \mid b \mid$ $\mid Z \mid < \mid a \mid$ $\mid a \mid < \mid Z \mid < \mid b \mid$
