Abstract
In color video switching equipment, the nature of the encoded signal requires that particular care be taken to achieve, over the frequency band, constant amplitude and delay, low differential gain and phase, and low crosstalk. Furthermore, performance must be independent of the number of output circuits connected to a particular input bus. Equipment meeting these requirements has been operating in CBS color-television studios in New York and Hollywood since August 1954. The objectives were achieved by adding back-contact loading to maintain constant capacitance on each input bus, by compensating this capacitance with loading coils in each input bus, by reducing capacitance coupling through contacts, and by minimizing distortion in output coupling amplifiers.
