This paper presents a design and implementation method for the linear phase 2-channel perfect reconstruction FIR filter banks with arbitrary filter length. In this method which we call weighted Lagrange-Newton method, by introducing the least squares weighting function into Horng's method (Lagrange-Newton method), the QMF (Quadrature Mirror Filters) with good stopband attenuation can be designed. Furthermore, we show the construction of the 2-channel perfect QMF that achieve perfect reconstruction in spite of coefficient quantization.
