Definitions:

Separator

In electrochemical cells, a separator is a membrane that allows the flow of ions but prevents direct contact between the cathode and anode, thus avoiding a short circuit.

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.
