Shielding, cable spacing, and earthing
A few practical methods of reducing noise will be examined in this technical article. These include a quantitative consideration of the effects of shielding, cable spacing, earthing (or grounding) and a note of specific problem areas on which to concentrate.

- Shielding and twisting wires
- Cable spacing
- Tray spacing
- Earthing and grounding requirements
- Specific areas to focus on
