**Question #7:** For the original bandlimited signal shown below, schematically draw the output frequency signal for the following three cases: **Case #1:** Sufficient sampling \((f_s = 2 \times f_{\text{max}})\); **Case #2:** Over sampling \((f_s > 2 \times f_{\text{max}})\); **Case #3:** Under sampling or aliasing \((f_s < 2 \times f_{\text{max}})\). --- **Original Signal Diagram:** The diagram is a graphical representation of a bandlimited signal in the frequency domain. It features a triangular-shaped spectrum centered at zero frequency. The spectrum extends symmetrically between \(-f_{\text{max}}\) and \(f_{\text{max}}\) on the frequency axis. The peak of the spectrum is denoted as \(X_a(\omega)\). Here, \(-f_{\text{max}}\) and \(f_{\text{max}}\) represent the maximum frequency limits of the signal.
