PURPOSE:To promote the compression of waveform data and freely control the compression. CONSTITUTION:The data compression is promoted more by performing not only a specific data compressing process for the waveform data, but also an arithmetic process for decreasing the value of the waveform data according to a weight coefficient before or after the data compressing process. The system of the specific data compressing processing itself is not altered and easily and freely controlled so that the compressibility can be varied or no compression is performed extremely easily only by varying the weight coefficient. This device and method are advantageous when the data compression is further promoted in some section of the waveform or when the data compression is performed to different extents according to sections of the waveform. |
