Abstract: In order to narrow the bandwidth of a communication channel through which electrical signals are to be transmitted the latter are passed through an electro-optical device comprising doublediffraction optical system employing monochromatic light. The double-diffraction system is equipped with an electro-optical modulator to which the electrical signals are applied and a photoelectric transducer collects the spatially modulated monochromatic light after filtering therefrom of certain spectrum components, the remaining spectrum components having been juxtaposed.
