- DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具,直接计算DFT的计算量与变换区间长度N的平方成正比。当N较大时,因计算量太大,直接用DFT算法进行谱分析和信号的实时处理是不切实际的。快速傅立叶变换(Fast Fourier Transformation,简称FFT)使DFT运算效率提高1~2个数量级。其原因是当N较大时,对DFT进行了基4和基2分解运算。FFT算法除了必需的数据存储器ram和旋转因子rom外,仍

Sample-Entropy-VB
- 样本熵是一种有别于近似熵的不计数自身匹配的统计量,是对于近似熵算法的改进。样本熵与近似熵的物理意义一样,表示非线性动力学系统产生新模式概率的大小,主要用来定量刻画系统的规则度及复杂度。样本熵值越低,序列自我相似性越高,产生新模式的概率越低,时间序列越简单;反之,样本熵值越大,序列自我相似性越低,产生新模式的概率越高,时间序列越复杂。样本熵计算用程序VB6.0语言实现。-Sample entropy is different from the research and development o
