What is the primary function of a receiver discriminator?

The primary function of a receiver discriminator is to detect frequency modulation (FM) signals and provide an output that represents the original information. This process involves converting the changes in frequency of the incoming FM signal into corresponding amplitude variations.

When an FM signal is received, it carries information in the form of frequency changes. The discriminator interprets these changes and translates them back into the original audio or data signal that was transmitted, enabling the receiver to reproduce the sound or data accurately. This output can then be further processed and amplified for listening or further use.

In the context of radio communications, this detection and conversion are crucial as they allow for the effective interpretation of the information contained in FM transmissions, which is characteristic of many broadcasting and communication systems.
