说明：  噪声中正弦信号的现代法谱分析，采用了直接法、间接法、Bartlett法和Welch法，分别分析了不同窗长度、不同窗函数和不同信噪比对谱估计的影响。(Modern normal spectrum analysis of sinusoidal signal in noise adopts direct method, indirect method, Bartlett method and Welch method. The effects of different window lengths, different window functions and different signal-to-noise ratios on spectrum estimation are analyzed respectively.)

说明：  matlab程序，用于提取脑电数据的五种频域特征指标数值(matlab code, Five Frequency Domain Characteristic Index Values for Extracting EEG Data)

BRC MATLAB code for BRC.fig BRC, by itself, creates a new BRC or raises the existing singleton*. H = BRC returns the handle to a new BRC or the handle to the existing singleton CALLBACK ,hObject,eventData,handles,...) calls the local function named CALLBACK in BRC.M with the given input arguments.BRC Property , Value ,...) creates a new BRC or raises the existing singleton.Starting from the left, property value pairs are applied to the GUI before BRC_OpeningFcn gets called.An unrecognized property name or invalid value makes property application stop. All inputs are passed to BRC_OpeningFcn via varargin.See GUI Options on GUIDE s Tools menu. Choose "GUI allows only one.instance to run (singleton)".Edit the above text to modify the response to help.Begin initialization code - DO NOT EDIT
