A Self-Phasing Rotational Synchronization System

A new general-purpose, pulse-multiplier technique, which uses cascaded monostable multivibrators to provide successive doubling of low-order pulse rates to a much higher frequency, is described. One important application of the pulse multiplier enables positive self-phasing for low cyclic rotational synchronization. It promises significant benefits in the multichannel, facsimile, and picture transmission fields. An operational breadboard model of a system as described gave a measured performance of ±0.5 degree phase angle deviation (transmitter to receiver).
