B.S.T.J. Briefs: Point-Contact Wafer Diodes for Use in the 90 - to 140- Kilomegacycle Frequency Range

THE BELL SYSTEM TECHNICAL J O U R N A L , S E P T E M B E R 1003 present. The clockwise rule to cover the situation shown in Fig. 1(d) is implemented by connecting the clockwise ac input to the unactivated contact on 1A. If none of the inputs is present, the local clock free runs but can still synchronize its clockwise neighbor. Description of a dc system was for simplicity of illustration. Other indications of priority could be employed: e.g., tone modulation with tuned reed relays for ac analog systems and simple codes for digital systems.
