A New Theory of Broad-band Matching
Dante C. Youla · IEEE Transactions on Circuit Theory · 1964
This paper solves the problem of designing an optimum, passive, reactive two-port equalizer to match out a dissipative frequency sensitive load to a resistive generator. The method is simple and elementary and completely avoids any recourse to the Darlington equivalent of the load. Moreover the technique is also applicable to the design of active equalizers.
