Abstract
The aim of the invention is to ensure joint utilization of the processing circuits of a demodulator of this kind, and hence save components. This is done by establishing a demodulation table for codewords which are altered compared with the n-bit codewords in the modulation table. The invention is particularly suitable for use in the recording of digital audio or video signals.
