Abstract: The multi-mode mean field annealing (MM-MFA) approach is introduced as an efficient tool to design digital filters with discrete coefficients, each implemented as a sum of signed power-of-two terms, and additional general hardware constraints.
As an application example demonstrating the potential of the new method we consider the design of a linear phase non-recursive (FIR) filter with a least squares criterion and minimum number of power-of-two terms.
