Abstract :
Analog circuits for eigenvalue calculation or rank filtering can be applied to real-time signal processing tasks. This paper reports on experimental results with an analog circuit for these applications. The circuit is based on a nonlinear dynamical system. Details of the realization including parasitic effects are discussed. The accuracy of the circuit has shown to be sufficient for image processing applications
