<emc-hardware-design>
The hardware measures describe means to improve EMC which can be realized with the use of hardware. Among these are, e.g.:
 
Filtration and protection wiring of inputs and outputs and supply conductions
 
Shielding measures
 
Printed circuit board layout
 
Integration of anti-interference capacitors
 
Influence of the different modes of operation (e.g. 2-wire-CAN)
 
Selection of quartzes
 
others
