A mathematical analysis of the pulse sampling and sorting processes is presented. Color distortion and cross talk introduced by sideband clipping of the sampled color functions is examined. A color multiplexing arrangement using cisoidal functions is described which can produce results equivalent to the pulse sampling and sorting method, and which is more economical circuitwise than pulse sampling. The use of mixed highs is reviewed and is shown to produce negligible effects on the color presentations, while providing resolution for the color picture equivalent to present monochrome standards in the same bandwidth.
