Definitions:

Cut-off Frequency

The frequency at which the magnitude of a signal is reduced by a specific ratio, marking the boundary between passband and stopband in a filter’s performance.

Variable Capacitors

Capacitors whose capacitance value can be adjusted or varied, often used in tuning circuits or as part of frequency modulating systems.

Variable Inductors

Inductors whose inductance can be adjusted or varied, often used in radio equipment for tuning and filtering applications.

Tuning

The process of adjusting the frequency of a receiver to match the frequency of the desired signal.
