real-time expert system for compression / decompression without distortion digitized analog signals.

摘要

EXPERT SYSTEM FOR REAL TIME COMPRESSION / DECOMPRESSION ANALOG SIGNALS WITHOUT DISTORTION digitalized. THE EXPERT SYSTEM BASED ON REORGANIZATION OF INFORMATION AVAILABLE AFTER Digitizing signals. THEREFOR codeset FROM DIGITAL discretization become another set of integers OBTAINED EACH OF THEM AS THE DIFFERENCE OF THE PREVIOUS digital code, assigning the value 0 to the first sample. (ORIGINAL DATA RECOVERY WARRANTED BRIDGING THE DIGITAL CODE OF INITIAL). COMPRESSION itself BE ON RESULTING FROM THE PROCESSING WHOLE. A DELAYED are coded according to method exploits the fact that 98% of the resulting distribution tends to be concentrated around 1% of the possible values ​​that always match AROUND THE NUMBERS 0. (SHOWN THIS FACT TO THE TRANSFORMATION resulting from digitalized signal 12 BITS). THE bitstreams thus obtained can be processed (storage, transmission, etc.) being secured recovery of raw data. This expert is applicable in all areas SYSTEM REQUIRING data compression. They have been achieved rates of over 80%.
