Digital audio signal transmission system - includes error correction and reduces redundancy by summing samples into sums to form data block

摘要

The transmission system has each signal sample grouped together into a sample sum comprising consecutive samples. The individual sample sums following one another in the direction of sampling are formed by summands displaced by one sample. The number of summands per sample at the start and end of a data block formed by several sample sums increases or decreases respectively in steps. The number of summands of a sample sum varies according to the certainty with which errors require correcting. The number of sample sums in a data block is variable.
