What type of interference prohibits signal clarity in conventional copper wires?

Electromagnetic interference (EMI) is the type of interference that significantly affects signal clarity in conventional copper wires. This occurs when electrical signals from nearby devices or sources—such as motors, radio transmitters, or even fluorescent lighting—create electromagnetic fields that can induce unwanted currents in the copper wires. These unwanted signals can distort the intended data transmission, resulting in noise, reduced performance, and loss of fidelity in audio and video signals.

Interference from EMI is particularly concerning in environments where numerous electronic devices operate simultaneously. Proper shielding and grounding techniques are often employed in cable designs to mitigate these effects, enhancing the clarity of the transmitted signals over copper wiring. This makes understanding and addressing EMI crucial for maintaining signal integrity in audio-visual installations.
