= Spectral correlation density
{wiki=Spectral_correlation_density}
Spectral correlation density is a concept used in the analysis of signals, particularly in the context of time series data and spectral analysis. It involves examining the correlation between different frequency components of a signal or between different signals in a frequency domain. In detail, spectral correlation density can be understood as follows: 1. **Spectral Analysis**: This involves transforming a time-domain signal into the frequency domain, typically using a Fourier transform.
