Definitions:

Discriminator

An electronic circuit used to demodulate frequency-modulated signals, converting changes in frequency into amplitude variations.

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.
