Design of 2D FIR digital filters with flatness constraints for the error function

  • Rudolf Rabenstein


A method will be presented for the approximation of a desired two-dimensional frequency response by the frequency response of a two-dimensional finite-impulse-response digital filter. It is possible to match the functional values and an arbitrary number of derivatives of both responses for zero frequency, thus making the error flat up to a desired degree. Remaining degrees of freedom are used for anL2-approximation. Closed form design formulae will be given.
