| 摘 要： | 首先简单介绍了小波变换消噪的原理,然后分别利用小波变换和傅里叶变换,对临床采集的脉象信号进行了消噪处理.结果表明,利用小波消噪能够有效地保留脉象信号中的尖峰和突变部分,最大限度地反映了原信号本身的特性,消噪效果较好.

| Abstract: | Firstly,this paper introduces the principle of wavelet transform in denoising simply,and then has the clinic pulse signal denoised by wavelet transform and Fourier transform respectively.The experimental results show that the pulse signal denoised by wavelet transform can effectively retain the pinnacle and mutation of pulse signal and embody the original pulse signal's character as soon as possible,the denoised result is better. |
