Sentences with phrase «red at lower frequencies»

Not exact matches

A log - log power spectra that displays 1 / f ^ 2 (red) trend at the lowest frequency limit, through to (and pass) 1 / f ^ 1 (pink), and ending up as 1 / f ^ 0 = 1/1 (white), or white noise at the upper (Nyquist) frequency limit.

You will see 1 / f ^ 2 at the low frequency limit (e. g. red noise) and at the upper limit 1 / f ^ 0 (e. g. white noise), in between it goes from red - > pink - > white.

It has enhanced variability, because averaging the reconstructions results in a redder time series (there is less common variance between the reconstructions at the higher frequencies compared with the lower frequencies, so the former averages out to leave a smoother curve) and the re-calibration is then more of a case of fitting a trend (over my calibration period 1881 - 1960) to the observed trend.»
