4. Principle of Operation
The GS38920000230 Repeater operates by receiving the Dupline signal from one segment of the network, regenerating it electronically, and transmitting it to the next segment. This process ensures that the overall signal strength and data integrity remain uncompromised even across long cable runs.
Dupline communication typically employs frequency shift keying (FSK) to encode data, which is inherently robust against electrical noise. The repeater’s regeneration circuitry further enhances this robustness by reconstructing clean signal waveforms and filtering out unwanted noise components.
