I try to implement the spatial spectrum from the above equation (attached) Where kX, kY are the grid points in k space, C(w,r) - cross spectral densities betwe
I want to create 10,000 sample (random phase but same power spectra) of my original time series using fourier transform. The method I want to opt is given in fi
I am using the following code to draw a curve from my two column Raw data ( x=time , y=|float data|).The graph it is plotting is a rough edge graph. Is it possi
