A salient feature of proposed method is the incorporation, as a design parameter, of a new variable

in the decomposition of the second-order polynomials. It has been shown that the performance criteria such as

sensitivity and

sensitivity are accordingly expressed as functions of

thereby leading to possible optimizations. The continuous change of the variable encompasses not only existing optimum decompositions but also a variety of other decompositions which may be regarded as optimum with respect to diverse performance criteria. Two types of decomposition corresponding to

: gyrator synthesis and

:NIC synthesis are used to demonstrate the proposed method.
