Decomposition of Heart Rate Variability Spectrum into a Power-law Function and a Residual Spectrum
The power spectral density (PSD) of heart rate variability (HRV) contains a power-law relationship that can be obtained by plotting the logarithm of PSD against the logarithm of frequency. The PSD of HRV can be decomposed mathematically into a power-law function characterized by the slope and Y-inte...
