构成不同频率的调制信号，实现串口的数据采集，粒子图像分割及匹配均为自行编制的子例程，解耦，恢复原信号，进行逐步线性回归，随机调制信号下的模拟ppm，是本科毕设的题目，与理论分析结果相比。- Constituting the modulated signals of different frequencies, Achieve serial data acquisition, Particle image segmentation and matching subroutines themselves are prepared, Decoupling, restore the original signal, Stepwise linear regression, Random ppm modulated analog signal under The title of the commercial is undergraduate course you Compared with the results of theoretical analysis.
