摘要：
The Lagrange multiplier approach has been widely used to design maximally flat, real coefficients FIR digital filters and differentiators. This paper extends this approach to design arbitrary complex coefficient FIR digital filters with arbitrary frequency response or derivative constraints. The method can easily be extended to design arbitrary two-dimensional complex FIR digital filters with arbitrary frequency response or derivative constraints, too. Several examples are presented to demonstrate the effectiveness of the approach.
