2.2 THE ELECTRO MAGNETICS FIELD PROTECTION
2.2.1 Circuits protection
To reduce the induced signals level on the wave e.m. wave is appealed to the appropriates interventions:
- reducing of the area of the hit circuit from the wave, that is the conductors approaching active and of return;
- in the printed circuits this impose the employment for more layer and for a distribute ground;
- resort to the balanced circuits;
- resort to the cables screened, better with a double screened, with the screen opportunely connected;
- resort to the co-axial cables, better semi-rigidi;
- resort to the screen from the intern circuit.
