Abstract
An approach to the design of linear-phase, maximally linear full-band and wideband differentiators with or without designated stopbands is proposed. The design is based on minimization of the integrated square error for the frequency response and is formulated as a quadratic programming problem with linear equality constraints. The closed-form solution is obtained by the method of Lagrange multipliers. Several design examples are included. They indicate significant improvement in low-frequency error when compared to similar designs based on the minimax criterion
