| 摘 要： | 简介小波概念之后,对一组模拟信号进行分析,采用小波变换,选出合适的小波函数,处理后再重构。对采用Mexican hat小波、Shannon小波、Meyer小波这三种不同小波得到的去噪结果进行比较,验证信号的滤波效果与选取的小波类型有较大的关系。 |
| 关 键 词： | 信号分析 小波变换 去噪分析 |

| 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. |
| Keywords: | signal analysis wavelet transform denoising analysis |
