Abstract
Abstract This method involves multiple formation of differences, these differences being coded in such a manner that those with a higher probability of occurrence are allocated shorter code words than those having a lower probability of occurrence. The number of differences formed is selected in such a manner that the coding of the differences results in a minimum of the mean code word length. In the digital processing of the signal values, this results in a reduction in the storage space required or in the transmission time. The invention is used in recording measuring instruments, particularly for network supervision. <IMAGE>
