Abstract :
A novel design method for signal flow graph (SFG) filters with finite zeros is presented. The method uses a minimum number of (equal) capacitors without excessively increasing the total number of components, which is an advantage for discrete implementation. Other filter characteristics, such as passive and active sensitivities, remain similar to those of the usual SFG filters
