Normalized Design of 90° Phase-Difference Networks

Abstract
The theoretical background exists for the design of 90° phase-difference networks. Continued interest in the design of such wide-band networks for single-sideband and other applications indicates the need for methods to ease the computational difficulties inherent in network design involving elliptic functions. Concise design data are given in the form of equations, curves and tables which simplify synthesis of LC or RC all-pass networks by eliminating the above computational difficulties. The normalized design curves presented cover a range of bandwidths of 2000 to 1 and permit the designer to write the response function of all-pass phase-difference networks with over-all complexity of up to 12 real pole-zero pairs.
