Screen Cables

All cables are subject to interference pickup as a result of electrostatic and electro-magnetic fields set up by nearby electrical wiring and equipment.
There are two basic types of external noise that affect cables:

• Electrostatic, from external high voltages
• Electromagnetic, from external high currents

The shield acts as a Faraday cage to reduce electrical noise from affecting the signals, and to reduce electromagnetic radiation that may interfere with other devices . The shield minimizes capacitively coupled noise from other electrical sources.

In shielded signal cables the shield may act as the return path for the signal, or may act as screening only. Braided cables are more effective at low frequency(EMI) and spiral wounded Aluminium tape are better at high frequencies (RFI).
