对脑电信号进行小波分解并重构，提取脑电信号不同频段的成分(Decompose EEG and then reconstruct it to get different component)

选择五个不同频段的信号对其进行频谱分析，根据信号的频谱特征设计五个不同的数字滤波器，将五路信号合成一路信号，分析合成信号的时域和频域特点，然后将合成信号分别通过设计好的五个数字滤波器，分离出原来的五路信号，分析得到的五路信号的时域波形和频谱，与原始信号进行比较，说明频分复用的特点。(To select one of five different band signal spectrum analysis and design of five different digital filter based on the spectral characteristics of the signal, the the Rd signal synthesizing all the way to the signal analysis in time domain and frequency domain characteristics of the synthesized signal, and then the synthesis signal by five digital filter designed, separated original signal Rd, the time-domain waveform and spectrum analysis the Rd signal is obtained, to be compared with the original signal, the frequency division multiplexed with the characteristics.)
