摘要 阐述了傅里叶变换(FFT)、短时傅里叶变换(STFT)以及小波变换的理论,并在MATLAB中对实验中自由活动大鼠运动皮层放电过程中采集到的数据进行了分析.实验表明,小波变换为脑电信号处坪领域的研究提供了一个更加有效的方法. The article introduces FFT, STFT and wavelet transformation method, makes analysis for the data obtained from the rat's brain local field potential, using MATLAB. The experiment shows that the method based on Wavelet Transform is more convenient and efficient in LFP processing field.
