GATE EC 2014 Set 4 Q18 — LTI Systems

A real-valued signal $x(t)$ limited to the frequency band $\mid f \mid \leq \frac{W}{2}$ is passed through a linear time invariant system whose frequency response is $H(f) = \begin{cases} e^{-j 4 \pi f}, & \mid f \mid \leq \frac{W}{2} \\ 0, & \mid f \mid > \frac{W}{2} \end{cases}.$ The output of the system is

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 …
