  Fourier analysis Information Fourier analysis is a mathematical technique used to represent a time series as a sum of sine and cosine functions with different frequencies. This technique allows us to decompose a complex signal into simpler components that can be easily analyzed and modeled. In time series forecasting, Fourier analysis is used to identify seasonal patterns or cycles in the data. The output of Fou.. Zettelkasten/Terminology Information 2023. 4. 12.
