Passive networks that produce polyphase output from single-phase input over wide frequency bands have great practical utility, yet published analysis of their action is incomplete. After reviewing properties of simple branch circuits useful in such networks, an expression is derived for phase difference produced between branches as a function of frequency. This expression is given a remarkably simple form, from which over-all operating properties are evident by inspection, permitting direct circuit design from required performance. General performance and design curves are presented.
