………………….. is the overlapping of frequency bands which can distort/wipe-out a signal.a.Distortionb.Attenuationc.Noised.Interference

Break Down the Problem

1. Identify the key concept in the question related to signal processing.
2. Analyze the provided options to determine which one matches the description of overlapping frequency bands affecting a signal.

Relevant Concepts

• Distortion: Alteration of the original signal resulting in an inaccurate representation.
• Attenuation: Reduction in signal strength during transmission.
• Noise: Unwanted random disturbances affecting a signal.
• Interference: Overlapping or mixing of signals, particularly in the context of signals from various sources leading to distortion or loss.

Analysis and Detail

1. Distortion: This typically occurs from factors affecting a signal, but does not specifically refer to overlapping frequency bands.
2. Attenuation: This is purely about weakening the signal, not overlapping frequencies.
3. Noise: While noise can overlap with signals, it refers more to random disturbances rather than consistent frequency bands.
4. Interference: This specifically addresses how signals can overlap and affect one another, particularly from multiple sources, leading to distortion or loss of the original signal.

Verify and Summarize

Upon analyzing the definitions and functions of each term, it is clear that "Interference" best describes the phenomenon where overlapping frequency bands distort or wipe out a signal.

Final Answer

d. Interference
