Fftfile-of-EEG
可以用FFT频谱对脑电信号进行提取。我们可以利用提取出的各个波段脑电信号,来诊断一些脑部疾病或者对大脑组织的电活动及大脑的功能状态进行分析。
1.将实验测得的脑电数据文件转换为文本文件(已经过50Hz陷波), 获得在Matlab 平台上可直接使用的脑电信号数据,即0661.txt。
2.在Matlab中导入数据,并提取Fp1通道的脑电信号,通过FFT变换对α,β,θ,δ波段进行提取,并做FFT逆变换变到时域。
3.计算各个波段的功率谱。(FFT spectrum can be extracted on EEG. We can use the extracted EEG each band to diagnose some brain disorders or brain tissue on the brain' s electrical activity and functional status were analyzed. One would experimentally measured EEG data file into a text file (has been 50Hz notch), obtained in Matlab platform can be used directly EEG data, that 0661.txt. (2) import data in Matlab and extract Fp1 channel EEG by FFT transform α, β, θ, δ bands were extracted, and do FFT inverse transform variable to the time domain. 3 calculate the power spectrum of each band.)

ECG-diag
MATLAB心电图自动诊断程序。围绕心电信号预处理、心电波形检侧与定位、心电特征提取与分析三个方面。研究MIT数据库中的心电信号,针对心电信号中存在的工频干扰、基线漂移、肌电干扰等各种噪声,设计出了高通、低通、带阻、平滑效果滤波器来对心电信号进行预处理,对处理后的信号采用连续小波变化进行特征点的定位及瞬时心率的计算,最后通过分析给出诊断结果。(MATLAB ECG automatic diagnosis program. Around the ECG signal preprocessing, ECG waveform detection and location, ECG feature extraction and analysis of three aspects, the study of MIT in the ECG signal. According to the frequency interference, baseline drift in the presence of ECG, EMG interference and other noise, design a high pass, low pass, band stop filter, smoothing effect of pretreatment of the ECG signal, the calculation of the processed signal using continuous wavelet transform to locate feature points and instantaneous heart rate, finally the diagnosis results.)
