Which mechanism causes aliasing when sampling an analog wave?

💡 Explanation

Aliasing occurs because the Nyquist-Shannon Sampling Theorem dictates a sample rate exceeding twice the highest frequency. Undersampling does not resolve the signal properly causing high frequencies to appear as lower frequencies; therefore, aliasing results, rather than accurate reconstruction.
