Abstract
Fundamental nonlinear filters including M-filters and order statistic filters are formulated generally by the maximum a-posteriori (MAP) est imation and some filters are derived with the aid of the Bayes formula . This MAP-filters reduces to M-filters if a-priori probability distri bution is uniform, while the rank filters are derived when a-priori bi as exists in the MAP estimation. This MAP-filters are implemented with an analog electronic circuit and the log-likelihood is shown to be a Liapunov function for the dynamics of this circuit.
