The power spectral density describes the extent to which sinusoids of a single frequency capture the structure of the data. To compute the power over any range ... ... <看更多>

There are many ways to estimate the power spectrum of a time-series. The simplest (and quite frankly, "worst") way to do this is a simple ... ... <看更多>

My plan to do this was 2a) take a 2d fft of data, calculate the power spectrum density 2b) some method?, 2c) take the 2d ifft of the modified ... ... <看更多>
