What does the term "aliasing" specifically refer to?

A) Signal distortion due to noise

B) Sampling errors in audio processing

C) Misrepresentation of high-frequency signals when sampled below the Nyquist rate

D) Redundant data in a signal

Answer: C) Misrepresentation of high-frequency signals when sampled below the Nyquist rate

Explanation: Aliasing occurs when high-frequency signals are sampled at a rate lower than the Nyquist rate, causing them to appear as lower frequency signals in the sampled data, leading to distortion.
