Hello, I am attempting to create a synthetic time series to perform spectral analysis (FFT and Lomb-Scargle) on. Ideally, this time series will have three frequencies in it plus noise. I can generate an artificial time series using rand function, but I do not know how to incorporate specific frequencies and noise (this seems like a different process than rand. Any help would be greatly appreciated!
