The soft threshold signal is sign(x) (|x| - t) if |x| > t and is 0 if |x| ≤ t. Hard thresholding can be described as the usual process of setting to zero the coefficients whose absolute values are lower than the threshold. Soft thresholding is different from hard thresholding in...
wavelet de_noising analysis method is presented.The study shows that with the method offered the useful information reflecting the condition of the reciprocating pump can be effectively extracted from the highly noised signal by soft_thresholding de_noising method at the power end of the reciprocating...
