Abstract
The "leap frog" active synthesis technique is generalized to include simulations of more generalLCladder networks such that a one-to-one correspondence' between reactive elements and active integrators is maintained. This is accomplished through the introduction of two special "port reciprocators" which together with a set of basic signal flow graph building blocks and a set of interconnection rules forms a complete active synthesis technique. A design example is presented and a method of reducing the number of amplifiers required is outlined.
