* <a href="page.php?w=Transmission_line">Transmission line</a> techniques for cables and wiring, such as balanced differential signal and return paths, and impedance matching.<br/>
* Avoidance of antenna structures such as loops of circulating current, resonant mechanical structures, unbalanced cable impedances or poorly grounded shielding.<br/>
* Eliminating spurious rectifying junctions that can form between metal structures around</p><p>
