Abstract

Signal processor for the processing of digital signals in the physical (for example, optical) domain. This is inter alia relevant for ATM systems in which control codes such as VPIs and VCIs at the inputs of sub-systems have to be changed. A symbol stream is lead through different delay branches. The number of delay branches is of such magnitude that at each moment, in at least one of the branches, both a "1" symbol and a "0" symbol is available. By the controlled opening and closing of the switches the symbol values can be changed. Moreover, no additional source of energy (light source) is necessary and the signal processor is completely transparent, that is to say, symbols at the output of the processor have exactly the same physical properties as those at the input of the processor. <IMAGE>
