 Amplitude of low frequency fluctuations

The amplitude of low-frequency fluctuations typically refers to the magnitude of variations or oscillations that occur within a signal or system at low-frequency ranges. In various fields, such as physics, engineering, and signal processing, this term can describe different phenomena depending on the context. 1. **In Time Series Analysis**: The amplitude of low-frequency fluctuations can refer to how much the signal deviates from its mean value over long periods.
