Definitions:

High-pass

A filter that allows frequencies higher than its cutoff frequency to pass through while attenuating frequencies below the cutoff.

Radio Station

A service that broadcasts audio content through radio waves to be received by the public, typically including music, news, and other entertainment.

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.
