WebMar 24, 2024 · 我之前一直以为totalscal的设置就是频率区间的大小， 如：totalscal设置45，以为显示的频率区间会是1~45HZ,但不是。 其实显示的是0~125HZ 才知道totalscal=45其实把频率段分成45份。显示的频率区间其实和脑电的采样频率有关，即如上面的fs=250，显示的区间是0~fs/2。 WebMATLAB short-time Fourier transform and wavelet change drawing time frequency graphics code, Programmer Sought, the best programmer technical posts sharing site. how much money does gronk have https://itsbobago.com
