The normalized Q-factors of the poles of an 8-th order elliptic filter with ξ=1.1 as a function of ripple factor ε. Each curve represents four poles, since complex conjugate pole pairs and positive-negative pole pairs have the same Q-factor. The Q-factor of all poles are simultaneously minimized at

It is recommended to name the SVG file “Elliptic8 Qfactor.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
