matlab终止以下代码生物医学工程 该存储库包含在2018-2019Spring在塞萨洛尼基的亚里斯多德大学电气与计算机工程学院教授的课程“生物医学技术”。 该项目是用MATLAB编写的。 该项目的目标是从EEG(脑电图)信号中进行尖峰分析和识别。 首先实现了一种尖峰识别方法。 然后进行特征提取,以便对代表特定神经元活动的峰值进行分类。 甲部 阈值方法通常用于检测经过300-3000Hz带宽滤波的细胞外记录的峰。 更具体地,使用宽度阈值,如果信号活性在附近超过阈值threshold的值,则检测该信号活性并将其记录为峰值。 问题_1_1 依次加载8个Data_Test_i.mat文件(i = 1,…,8),并为每个文件获取前10,000个样本。 然后绘制它们的图。 我们观察到,当我们继续进行下一个采样时,噪声会增加。 尖峰计数器: 阈值方法通常用于检测经过300-3000Hz带宽滤波的细胞外记录的峰。 更具体地,使用幅度阈值,检测信号活动并将其记录为尖峰,其中在附近它超过阈值
