Linear coherence
Did you know?
In signal processing, the coherence is a statistic that can be used to examine the relation between two signals or data sets. It is commonly used to estimate the power transfer between input and output of a linear system. If the signals are ergodic, and the system function is linear, it can be used to estimate the … Se mer The coherence (sometimes called magnitude-squared coherence) between two signals x(t) and y(t) is a real-valued function that is defined as: $${\displaystyle C_{xy}(f)={\frac { G_{xy}(f) ^{2}}{G_{xx}(f)G_{yy}(f)}}}$$ where Gxy(f) is the Se mer Here we illustrate the computation of coherence (denoted as $${\displaystyle \gamma ^{2}}$$) as shown in figure 1. Consider the two … Se mer Coherence has been found a great application to find dynamic functional connectivity in the brain networks. Studies show that the coherence between different brain regions can be changed during different mental or perceptual states. The brain coherence … Se mer If the signals are non-stationary, (and therefore not ergodic), the above formulations may not be appropriate. For such signals, the concept of coherence has been extended by … Se mer • Bicoherence • Scaled Correlation • Normalized cross-correlation Se mer Nettetlinear coherence Z.

Nettet12. jan. 2015 · A coherence of 1.0 means the output is perfectly explained by the input (i.e. the system is linear and the Hxy (f) measurement is perfect). A coherence of 0 means the output and input are totally unrelated. Values in-between state the fraction of measured output power explained by the measured input power and a linear process.
