Title:
SPIKE NOISE ELIMINATION METHOD USING AVERAGING REPETITION METHOD AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2005/043085
Kind Code:
A1
Abstract:
[PROBLEM] To provide a method and a computer program for detecting and eliminating two or more continuous spike noises without generating a data waveform distortion. [MEANS FOR SOLVING PROBLEMS] For data on points collected through physical measurements, many points near the maximum value and the minimum value in the spike noise range are selected for elimination. By using an averaging repetition method, which replaces the values of individual elimination-selected points with the average value of data near the elimination-selected data, two or more continuous spike noises are detected and eliminated.
