Abstract:
A process for preparing sampled values represented as two's complements for:a) removing least significant bits (LSB) by two's complement clipping;b) adding synchronization information (s(k)) in place of the least significant bits removed by the two's complement clipping in step a),wherein an average value of the synchronization information after clipping is given by the following formula (1)s(k)=(1/2)(q.sub.2 -q.sub.1) (1),wherein q.sub.1 is a quantization step of the sampled values prior to clipping and q.sub.2 is a quantization step of the sampled values after clipping, and the synchronization information (s(k)) is periodic and has dominant spectral lines for frequencies (f) greater than zero which are outside a useful spectrum thereof.
