From the project

Fabricatable version based on https://www.qsl.net/w2aew/W2AEW_NTSC_to_scope.pdf

This repository is a KiCAD transcription of a circuit by Alan Wolfe.

The following circuit converts a composite signal and splits the signal as such that it can display video on analog-style oscilloscopes using X,Y & Z inputs.

- LED indicator - Used for monitoring power - Power jacks/pads - choice between barrel jack or 3.96mm headers - BNC connectors for inputs and outputs
