H03M0007240000 Conversion to or from floating-point codes 1
H03M0007260000 Conversion to or from stochastic codes 1
H03M0007280000 Programmable structures, i.e. where the code converter contains apparatus which is operator-changeable to modify the conversion process 1
H03M0007300000 Compression (speech analysis-synthesis for redundancy reduction G10L0019000000; for image communication H04N); Expansion; Suppression of unnecessary data, e.g. redundancy reduction 1
H03M0007320000 Conversion to or from delta modulation, i.e. one-bit differential modulation 1
H03M0007340000 adaptive 1
H03M0007360000 Conversion to or from differential modulation with several bits, i.e. the difference between successive samples being coded by more than one bit 1
H03M0007380000 adaptive 1
H03M0007400000 Conversion to or from variable length codes, e.g. Shannon-Fano code, Huffman code, Morse code 1
H03M0007420000 using table look-up for the coding or decoding process, e.g. using read-only memory 1
H03M0007440000 Suppression of irrelevant zeroes 1
H03M0007460000 Conversion to or from run-length codes, i.e. by representing the number of consecutive digits, or groups of digits, of the same kind by a code word and a digit indicative of that kind 1
H03M0007480000 alternating with other codes during the code conversion process, e.g. run-length coding being performed only as long as sufficiently long runs of digits of the same kind are present 1
H03M0007500000 Conversion to or from non-linear codes, e.g. companding 1
H03M0009000000 Parallel/series conversion or vice versa(digital stores in which the information is moved stepwise G11C0019000000) 1
