Definitions:

Low Impedance

A characteristic of a circuit that allows a large amount of current to flow due to its low opposition to the current flow.

Opposition To Current

Resistance or any impedance facing the flow of electric current in a circuit, hindering the movement of charge.

Low-pass

A filter designed to allow signals with a frequency lower than a certain cutoff frequency to pass through while attenuating frequencies higher than the cutoff frequency.

Notch Filter

A filter designed to remove or significantly reduce the strength of a specific frequency or range of frequencies from a signal.
