Which of the following statements is correct?
[I.] All periodic signals are energy signals while aperiodic signals are power signals[II.] Periodic signals have finite and non-zero average power[III.] Both periodic and aperiodic signals have infinite power and energy[IV.] All periodic signals are power signals while aperiodic signals are energy signals
The overall impulse response of the system shown in figure is given by (Block diagram provided: Input $X(n)$ splits. One path goes to $h_1[n]$, another to $h_2[n]$. The outputs of $h_1[n]$ and $h_2[n]$ are subtracted. This result is convolved with $h_3[n]$. Separately, $X(n)$ also goes to $h_5[n]$. The output of $h_3[n]$ and $h_5[n]$ are subtracted. This result is convolved with $h_4[n]$ to produce $y(n)$.)
