| Abstract: | Physical experiments often involve large amount of data acquisition. In some circumstances, data compression is highly required to save the precious storage media. Since the physical data are often continuous, a new kind of data compression method is introduced to take advantage of the continuity.This method includes a differential calculation and sign bit coding and presents about 40% savings. |
