本程序是本人做的项目中的核心部分，在一定噪声干扰情况下，提取一到两个周期的离散信号为依据，进行谐波分析，分析出复杂波的基波高点，为后续打标做准备。花了本人一个月的功夫。-This program is a project I did in the central part of noise in certain circumstances, the extracted one or two cycles discrete signal based on harmonic analysis and the complex wave fundamental high point of marking to do for follow-up preparation. I spent a month in martial arts.
