Abstract :
The influence of the autonomic nervous system on the heart rate signal is interpreted as a frequency modulating signal which is composed of two opposing sources: the sympathetic and the parasympathetic systems. A derivation of a theoretical method for extracting the power spectrum of this compound modulator is presented together with experimental results. The estimation method is generally developed, providing an alternative formulation for power spectrum estimation of modulated random processes which follow certain limitations
