A Static Multispeed Synchro Switch

Limitations of switching circuits for multispeed synchro systems have prompted a systematic investigation of the switching problem. A basic circuit, repeated for each synchro, was designed to satisfy the requirements. The resulting network is a passive unit which, by use of diodes and resistors, provides for inherently fast and reliable switching and, furthermore, eliminates all errors except those which are introduced through the final synchro.
