Abstract
An approach to the design of linear-phase FIR (finite impulse response) bandpass filters is presented. Their design is based on the minimization of the integrated square error for the frequency response while maintaining maximal flatness at the passband center. The closed-form solution for the filter coefficients is obtained by the method of Lagrange multipliers. A design example is included which demonstrates the effectiveness of the technique
