A simple analog rank filter
Steffen Paul, Knut Hüper, Josef A. Nossek · 2003
A simple analog rank filter structure is proposed. A matrix-valued ordinary differential equation (ODE) with initial conditions performs the sorting. The state realization of this ODE contains integrators, adders, and multipliers. The multiplication operations make the filter nonlinear. The structure is a regular array that is only locally connected.>
