Abstract
1. Arrangement for the conversion of codewords (CW) of varying length into datawords (DW) of constant length, characterized in that a demultiplexer (DMUX) is provided, to which the codewords (CW) are fed in parallel form, in that the outputs of the demultiplexer (DMUX) are connected to parallel inputs (EP) of a memory register (R2), in that the parallel outputs (AP) of the memory register (R2) are connected via a dataword-multiplexing device (MUX) to data inputs (E7) of a memory (ME) and in that control devices (ST1, ST2) are provided for the demultiplexer (DMUX), the dataword-multiplexing device (MUX) and for the memory (ME).
