Question

Hi, I want to know how to convert RGB (Analog Component) Signal to Analog Composite Signal.I want to know the formula and method to convert it.

Answer 1

As lee b said

a) Use the formula to translate RGB to YCbCr (easy to find on the web)
b) Composite combines Y and Chroma (CbCr) into a single cable - Color then is retreived using a comb filter

So, you need some circuitry, which actually you can get.

Answer 2

you cant they are seperate signals on a rgb.the signal for composite is an encoding of all three.maybe grouping all of the wires of the internal red green and blue cables and all the outside grouped if you know what i mean.
