A design technique for linear phase recursive digital filters with controllable magnitude at an arbitrary specified frequency is presented. This technique uses the power series expansion to form a set of simultaneous linear equations. Then the filter coefficients can be obtained by solving these linear equations with a standard computational algorithm.>
