Signal switching with magnetic elements

The complex properties of square-loop magnetic devices allow them to be used in a surprising number of different applications. Multipath magnetic elements, in particular, can be used to achieve nondestructive memory-read systems, as well as all magnetic logic systems in which networks of such elements are interconnected with only ordinary electric wire.

In this paper, another capability of magnetic elements is presented which further increases the spectrum of magnetic circuit possibilities; this is the use of magnetic elements for switching analog signals.
