Splitters

A splitter is a passive device used to split signals. It is completely passive, i.e. it does not need electrical power.

If two types of waveforms with different frequency ranges are transmitted in a single cable, the splitter allows them to be separated from each other. It usually has one input and two outputs, as it splits the signal into two signals with different carrier frequencies. Inside, the splitter contains two band-pass filters, and their characteristics are chosen so that only the appropriate signal goes to each output.
