Chrominace subcarrier refers to a separate subcarrier signal that carries the color information during transmission of a video signal. It is modulated and synchronized using the colorburst signal and then attached to the back porch of the composite color video signal. By synchronizing the subcarrier with the local oscillator of the receiver, the RGB colors can be decoded successfully.


tuned trap Typical values for the collector resistor and filter capacitor are 3 9K ohms and 33 pF I m using a 5 6K collector resistor so I proportionately reduce the capacitor to 22 pF
