Witryna20 cze 2016 · The real part for each frequency f is then calculated by: A (f) = sum from i=0...i-1 { (y_i+1 - y_i)/ (x_i+1 - x_i) * [ cos (2*pi*f * t_i+1) - cos (2*pi*f*t_i) ]/ ( (2*pi*f)^2) } The imaginary part is: A (f) = y_0/ (2*pi*f) + sum from i=0...i-1 { (y_i+1 - y_i)/ (x_i+1 - x_i) * [ sin (2*pi*f * t_i+1) - sin (2*pi*f*t_i) ]/ ( (2*pi*f)^2) } WitrynaIt works quite similar to a FFT or DFT, but it will only calculate the frequency at per-determined frequencies, and it could handle missing data, should that be an issue. The idea is as follows: Decide a list of frequencies ($w$) over which to calculate, that fit the desired frequency bands you wish to sample at.

WitrynaMy image is logarithmic. The default interval between frequencies is too big in the lower part of the frequency spectrum. So I just upped the number of frequency samples via the nperseg parameter. In this example, the distance between successive frequencies is 1 Hz, which is pretty good resolution. Also, symlog scaling is best. Witryna22 maj 2024 · The linear frequency scale makes the capacitor change difficult to see.
