How would I convert a black and white mechanical TV system to full color?
ANSWER. What you need are three copies of just the video part of the your circuit. Or you can use my circuit from the Web page. My circuit doesn’t have gamma correction and DC restoration, though. The circuit works anyway. With direct coupling, you can eliminate the DC restoration requirement. Run each color signal to its own amplifier. The circuit doesn’t need to I and Q (or U and V) encode or decode the signals. You have plenty of bandwidth, because everything is closed circuit. The colors occur simultaneously. For that reason, you also don’t need a field-sequential color wheel. Of course, the input signal must be a color TV signal. Converting a black and white signal would be an experimental effort. The late Nam June Paik was a member of our Experimental Television Society. Nam pioneered artistic color conversions of monochrome, NTSC TV pictures. I believe that the results were surreal, rather than naturalistic. That is, an artificial process derived arbitrary colors. Nam’s circuits
