Feeding technique for a stream of digital data by means of support in a transmission medium with frequency rejection and corresponding einpeiseschaltung

摘要

Feeding technique for a stream of digital transmission data (ü) in a transmission medium (3),– with a feeding circuit (1) with a stream of digital payload data (n), against,– wherein the injector circuit (1) the digital useful data (n) at predetermined first points (5) in the stream of digital transmission data (ü) is interposed,– wherein the injector circuit (1) on the basis of the current of digital payload data (n) digital supplementary items of data (e) is generated,– wherein the injector circuit (1) the digital supplementary items of data (e) at predetermined second locations (6) in the stream of digital transmission data (ü) is interposed,– wherein the injector circuit (1) the stream of digital transmission data (ü) into the transmission medium (3), feeds,– wherein the injector circuit (1) the digital supplementary items of data (e) determined in such a way that the proportion of at least one frequency different from zero (f) at a frequency spectrum of the current of digital transmission data (ü) is minimized.
