The Impedance Product Operator can be implemented in a number of embodiments
to produce a new non-reciprocal (n+1)-port network element with the distinguishing
property that if n 2-termial impedances, Z2, . . . Zn+1 are
connected at ports 2, . . . , n+1 of an Impedance Product Operator, the input impedance
offered by this loaded multi-port at port 1 is
##EQU1##
As a single network element, the Impedance Product Operator offers a direct yet
general mechanism for multiplication of 2-terminal impedance functions. This network
element allows simpler and more direct synthesis of driving point impedance functions.
