Estimation of Coherence and Cross Spectra

August 10, 2019 by

Coherence and cross spectra are powerful tools for evaluating the relationships between different signals. In practice they must be estimated from measured data. In this lesson you will learn how to estimate coherence and cross spectra using the principles of Welch's method for power spectrum estimation. You will also gain an understanding of how parameters like segment length and the number of segments impact estimator performance.
