A method is proposed for the design of two-channel linear-phase FIR QMF banks satisfying prescribed reconstruction and stopband errors. The method is integrated with a weighted minimax design of QMF banks based on an iterative method proposed by Chen and Lee (1992) with certain modifications based on the weighted least-squares (WLS) updating scheme proposed by Sunder and Ramachandran (1994). The method is simple and a design example is presented
