Research on Flatness Signal De-noising Based on Wavelet Theory

Abstract

On the basis of wavelet transform theory, using computer to simulate ∞atness signal with noise emerging in all kinds of environment, through the analysis of wavelet basis, decomposition scale and threshold rules, the actual ∞atness signal is extracted, which not only provides evidence for the improvement of ∞atness gauge accuracy, but precisely describes ∞atness ∞aw thus laid better foundation for the real-time control of ∞atness.
