COMPRESSION OF DIGITAL MEASUREMENT SIGNALS BY REVERSE SCALING RECONSTRUCTION METHOD

Jerzy Jurkiewicz, Waclaw Gawedzki
Abstract:
It is noticed in the paper that scaling of digital measurement signals during computer processing increase their volume so that after using standard compression methods it is impossible to obtain the volume of the compressed original signal. A reverse scaling operation with reduction of numeric errors is proposed as the method preceding compression. The operation restores the original signal and, therefore, restore the original signal volume. The rule of encoding measurement results into a certain number of significant digits is ecalled. The binary version of this rule is presented and it is observed that its application improves signal compressibility.
