a recording of the cardiac-induced skin potentials at the body’s surface
called heart rate variability, the variability of the RR-interval sequence
where λ is the mean number of events per unit time.
Here τd is the dead time and λ is the rate of the process before dead time is imposed.
w(ax) = g(a)w(x).
w(x) = bg(x) with g(x) = xc
g(x; a) = xc cos[2πln(x)/ ln(a)]
