Increasing information content of digital transmissions - involves transmitting measuring signals in series of subgroups

摘要

An increase in the data content of digital transmissions from analogue to digital converters coupled to measuring transducers, is obtained by separation into a coarse and fine component. The digitised measured parameter is of 12 bits length (MW) and is stored in such a way that the least significant bits are zero. The remaining bits (GR) form a coarse component that is checked against the stored value. If the difference is below a specified value the fine component is considered (FE). An eighth bit distinguishes the two groups.
