摘　　要：论述了小波分析在微重量动态称重信号降噪中的应用。主要分析如何引入小波变换理论,并通过小波去除微重量动态称重信号中的噪声。阐述了小波分析去噪及其相对FFT除噪方法的优势。结果表明,用小波变换处理含噪信号,具有明显效果。The denoise application of wavelet analysis in the dynamic weighing system is analysed.The theory of wavelet transform was firstly introduced,and removing the noise of weight signal using wavelet was further presented.The comparison between wavelet analysis and FFT is done to show the advantages of wavelet analysis in denoising.The results shows that the wavelet transform has remarkable effect in dealing with noisy signals.
