In a normal colour TV signal these are mixed together.
This leads to
several problems, including the fact that colour artifacts can occur with
arrays of vertical lines in the image (CoCo owners will have seen this -
and used it to get more colours). And that the luminance resolution
(bandwidth) has to be limited to prevent the colour subcarrier from
causing annoying moving lines in the image.
Is this what causes the infamous dot-crawl on the Spectrum?
