Question

Which of the following is the process of ‘aliasing’​

Answer 1

Explanation:

Explanation: Aliasing is defined as the phenomenon in which a high frequency component in the frequency spectrum of the signal takes the identity of a lower frequency component in the spectrum of the sampled signal.

i hope it helps to you

Answer 2

Spectral overlapping is the process of ‘aliasing’​

Explanation:

• Aliasing is defined because the phenomenon during which a high frequency component within the frequency spectrum of the signal takes the identity of a lower frequency component within the spectrum of the sampled signal.
• Aliasing can occur if either of the subsequent condition exists:
• The signal isn't band-limited to a finite range.
• The rate is just too low.
