FCC Finalizes Rules for Broadband from Wall Sockets
The Federal Communications Commission affirmed its rules for Broadband over Power Lines with minor modifications. The new rules provide a balance between providing for Access BPL technology that has potential applications for broadband and Smart Grid while protecting incumbent radio services against harmful interference. The rules have been modified “to increase the required … [Read more...]
Designing Electronic Systems for EMC: Grounding for the Control of EMI
There are two primary reasons for grounding devices, cables, equipment, and systems. The first reason is to prevent shock and fire hazards in the event that an equipment frame or housing develops a high voltage due to lightning or an accidental breakdown of wiring or components. The second reason is to reduce EMI effects resulting from electromagnetic fields, common impedance, … [Read more...]
