摘要
介绍了小波分析方法在人体振动信号处理中的应用.通过对采样频率相对较高、用于舒适性评价的信号进行数字低通滤波,采用等间隔抽取数据的方法获取采样频率相对较低、用于运动病评价的样本数据,以减小用于运动病评价数据的存储量和信号分析的运算量.
The theory of wavelet analysis and the digital filter for vibration signal processing was introduced. A low-pass filter could be applied to filtering the signal using wavelet transfer. After signal reconstructing and digital sampling, a new data sample only including low frequency was got.
