Coherence (signal processing)

ID: coherence-signal-processing

In signal processing, **coherence** is a measure of the correlation or relationship between two signals as a function of frequency. It quantifies the degree to which two signals are linearly related in the frequency domain. Coherence is particularly useful in the analysis of time series and signals where one wants to assess the extent to which different signals share a common frequency component. **Key Aspects of Coherence:** 1.
