I am new to high speed design .Please don't flame me if this question is very basic ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Below statement is from AD application note.
But it does not explain how this is happening.I have 2 questions.
1 ) May I know how ground plane acts as a low impedance return path.
2 ) Shelding action of GND plane.

Below statement is from AD application note.
"The ground plane not only acts as a low impedance return path for decoupling high-frequency currents (caused by fast digital logic) but also minimizes EMI/RFI emissions. Because of the shielding action of the ground plane, the circuit’s susceptibility to external EMI/RFI is also reduced."
