Synchro Data Quantizer and Digital Servo
Abstract
Because of the close coordination required for the exercise of integrated command in modern warfare, there is need for a dependable method of transmitting shaft-position data by means of narrow-band communication facilities. Such equipment could be used for ship-to-ship or ship-to-air transmission of angle and range information from radar and sonar installations. As a part of its program in this field, the Bureau of Ships (Code 832) established a project at the Naval Research Laboratory in May 1949 to investigate the application of digital techniques to the data-transmission problem.The immediate objection of the NRL project was to develop a Quantizer and Digital Servo for demonstrating a feasible approach to a digital data-transmission system. The Quantizer was to transform the shaft position of a synchro generator to a pulse-coded voltage. The Quantizer was to transform the shaft position of a synchro generator to a pulse-coded voltage. The Digital Servo was to accept this voltage and position a shaft to correspond with the synchro-generator rotor position. No radio link was used since it was known that transmission of the coded information could readily be handled by a a standard Navy communication facility. A model of the Quantizer and Digital servo was set up to demonstrate one-speed transmission of shaft rotation at the Symposium on Electronic Systems Integration held at the Naval Research Laboratory on 22 March 1950.
