Signal aliasing results in:
A) the sampled signal representing the original input signal.
B) the sampled signal having a frequency that is half the original input signal.
C) the sampled signal having a frequency that is twice the original input signal.
D) the sampled signal having a frequency that is equal to the difference between the sample frequency and the incoming signal frequency.

Question

Quizplus · Accepted Answer

Signal aliasing occurs when the sampling frequency is less than twice the highest frequency of the input signal, leading to a sampled signal that appears to have a lower frequency than the original. This phenomenon is described by the difference between the sampling frequency and the incoming signal frequency, as per the Nyquist theorem.
