Pink Noise #10

Closed lllx125 closed 4 months ago

lllx125 commented 4 months ago

I wrote the code to generate pink noise from a given beta, where the spectrum is (1/f)^beta, and a given number of points. The algorithm is given by "Timmer, J. and Koenig, M.: On generating power law noise. Astron. Astrophys. 300, 707-710 (1995)". Test the spectrum by using plotspectrum function in PlotTimeSeries.jl

I couldn't make packages and modules work, so to test it, you need to write include("src/SimUtils.jl") using .SimUtils plotspectrum(gen_pinknoise(1.0))
