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 ...
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 ...
Abstract: The design of complex digital signal processing systems implies to minimize architectural cost and to maximize timing performances while taking into account communication and memory access ...
