You may wonder what does FFT mean, you may want to use some of its value in the GUI but don’t know where and how, you may want to reimplement the good-looking FFT from the GUI to Matlab for future use ...

This code is based on a filter designed with below filter coefficients. The FFT on a real signal (w/o imaginary elements) is perfectly symmetric. Real signal = The abs value of FFT It also could be ...

Since I’m studying the spectrum characteristics of brainwaves with FFT in Matlab, I want to apply my algorithm later into OpenBCI GUI. Knowing that OpenBCI Processing GUI uses Minim to compute FFT, I ...

the ordering of the frequency vector is confusing due to the negative frequencies (spectrums are symmetric) the coefficients are not scaled as in a Fourier series due to the definition of the DFT The ...
