Which of the following would NOT help mitigate radio frequency interference?

Minimizing wire separation would not help mitigate radio frequency interference (RFI). In fact, reducing the distance between wires can often exacerbate interference issues. This is because when wires are placed too close to one another, they can couple signals, leading to crosstalk and the potential for increased interference. Proper spacing is essential to reduce the potential for RFI, as greater separation allows for better signal integrity and less impact from external electromagnetic fields.

On the other hand, using shielded cables provides a physical barrier that blocks external radio frequencies from affecting the signals within the cable. Optimizing cable layout can help by placing cables in such a way that they are less susceptible to interference, such as keeping them away from sources of RFI. Increasing wire thickness, while it may offer some benefits in terms of lowering resistance and improving performance in certain contexts, does not directly address the issue of RFI mitigation. Thus, keeping sufficient wire separation is critical to maintaining the integrity of the communication signals.
