Ground Noise: Circuit noise caused by a faulty
ground connection.
Ground Plane: A conductive pad on the printed
circuit board (see Figure 12), set at ground potential,
upon which a power supply is mounted.
Shields system components from possible RFI
noise generated by the supply.
Ground Potential: Potential of the ground point
in a circuit as referenced to other circuit voltage
levels.
Ground Resistance: The DC resistance of a
connection to ground or earth.
Ground Return: The circuit point or path used as
a return to ground (to compete the circuit).
