Signal path CBS signal

For the CVBS signal, the color information of the colors green, red and blue is transmitted across a single cable. The signal path has three important points that are independent of the image transmitted at that moment. This is why these points are used for measurement

For measurement, the following voltage differences must be examined.

Difference With adapter Without adapter
