Definitions:

Resonator

A device or system designed to oscillate with maximum amplitude at a specific frequency, often used in electronic circuits to select particular frequencies from a complex signal.

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.
