An l/sub 1/-approximation based method for synthesizing FIR filters
Wen‐Shyong Yu, I‐Kong Fong, Kuang‐Chiung Chang · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 1992
A method is proposed for the synthesis of digital filters having approximately the desired linear phase frequency responses. A mathematical optimization problem is formulated from the synthesis objective, and a theorem from the theory of l/sub 2/-approximation is used to convert the optimization problem such that it can be solved by the linear programming technique. The method is successfully applied to the synthesis of a digital FIR equalizer for a given analog antialiasing filter.>
