介绍 物种系统发育树(Phylogenetic tree),也称为进化树或系统进化树,是一种以树状分支图形来表示各物种或基因之间的亲缘关系的图表。它利用生物的形态特征、分子序列(如DNA、RNA或蛋白质序列)等数据,通过数理统计算法来计算生物之间的进化关系,从而构建出一个反映物种进化历史的拓扑结构。 构成要素 系统发育树由节点(...

数字信号处理(DSP),是指将连续的模拟信号转换为不连续、离散的数字信号并进行处理以提取所需的信号(信息)的过程。然后通过一个简单的Lab来说明DSP库文件的使用方法和功能实现。 DSP系统工程如下 将模拟(连续)信号转换为数字信号。 通过专用DSP、MCU等对信号进行处理(噪声滤波、频率分析等),并提取所需信号。
