A method of processing an input signal that includes an input variable is disclosed. The method comprises comparing the input variable to a set of ordered constants, determining the relative location of the input variable within a range of possible inputs and determining a filter coefficient of a nonlinear filter using the relative location of the input variable. A configurable filter comprises an interface configured to receive an input signal that includes an input variable, a nonlinear filter coupled to the interface, configured to process the input signal, and a processor coupled to the nonlinear filter, configured to determine the relative location of the input variable within a range of possible inputs and to determine a filter coefficient of the nonlinear filter using the relative location of the input variable.
