Consider the discrete-time system below with input $x[n]$ and output $y[n]$ . In the figure, $h_{1}[n]$ and $h_{2}[n]$ denote the impulse responses of LTI Subsystems $1$ and $2$ , respectively. Also, $\delta[n]$ is the unit impulse, and $b>0$ . Assuming $h_{2}[n] \neq \delta[n]$ , the overall system (denoted by the dashed box) is …
