Abstract: After the introduction of wavelet concept, using wavelet transform, the paper analyzes a group of simulation signals, chooses suitable wavelet function, then processes and reconstructs wavelet. Comparing three kinds of signal denoised by Mexican hat wavelet, Shannon wavelet and Meyer wavelet, the paper verifies the existence of a big concern between the effect of filter and selection of wavelet type.

Key words: signal analysis, wavelet transform, denoising analysis
