发明名称 NOISE SUPERPOSITION QUANTITY EVALUATING METHOD, METHOD AND APPARATUS FOR NOISE SUPPRESSION, NOISE SUPERPOSITION QUANTITY EVALUATING PROGRAM, NOISE SUPPRESSING PROGRAM, AND RECORDING MEDIUM WHERE NOISE SUPERPOSITION QUANTITY EVALUATING PROGRAM OR/AND NOISE SUPPRESSING PROGRAM IS/ARE RECORDED
摘要 PROBLEM TO BE SOLVED: To propose a noise suppressing method of surely removing influence of momentarily changing noise. SOLUTION: In the noise suppressing method of finding a signal from which influence of noise superposed on respective pieces of linear signals having one or more peaks from the pieces of linear signals, a weighted mean of entropy of the respective signals is found by using weight having a larger value as the number of peaks derived from entropy values of the respective signals showing whether much noise is superposed or not is larger to find the signal from which the influence of the noise is removed.
