Abstract :
The synthesis of N-order filters with N transmission zeros at real frequencies by means of extracted poles is presented. A procedure to extract the circuit elements that implement the finite insertion losses for infinite frequency is explained. To verify this procedure, three different implementations of a fourth-order filter with four transmission zeros are presented.
