该网络的特点是采用了技术成熟、价格低廉的非互易铁氧体移相器作为变极化的基础元件。
The feature of this network is that the cheap and mature nonreciprocal ferrite phase shiftersare used as the basic variable polarization devices.
本文首先阐述移相器的工作原理，然后讨论以移相器为基础构成的逻辑元件的原理。
The principle of operation of phase shifter is described first, followed by discussion of the principle of logic elements formed on the basis of the phase shifters.
