Abstract
The invention relates to a circuit arrangement for passing of blocking signals having wide band width with the use of at least one electronic switch. The circuit is a very simple arrangement, and provides for a plurality of modulators, or at least one modulator prior to the switching, and wherein the electronic switch is utilized is a logical linkage. The circuit is particularly adaptable for use in television circuits for distributing television signals.
Claims9
A circuit arrangement for selectively connecting a plurality of input lines to a plurality of output lines for passing or blocking wide band modulated carrier signals which are pulse, phase, pulse duration, pulse phase, or pulse frequency modulated, comprising a plurality of modulators to which said plurality of input lines are connected and performing modulation on signals passing therethrough, an electronic switching matrix with a plurality of row and column lines which cross each other with electronic switching means at the crossing points, the outputs of said plurality of modulators connected to said plurality of column lines, a plurality of optical transmitters connected to said plurality of row lines, and a plurality of output lines connected to said plurality of optical transmitters.
