Question

physical significance of spectral overlap integral in energy transfer studies?​

Answer 1

Adaptive filters can be applied to signal-changing environments, spectral overlap between noise and signal, and unknown or time-varying noise.

2.

Wiener filter theory provides optimal weight solution based on statistics. It involves collection of a large block of data, calculation of an autocorrelation matrix and a cross-correlation matrix, and inversion of a large size of the autocorrelation matrix.

3.

The steepest decent algorithm can find the optimal weight solution using an iterative method, so a large matrix inversion is not needed. But it still requires calculating an autocorrelation matrix and cross-correlation matrix.
