Synchro data transmission systems can be categorized into the two following basic systems: 3.3 Synchro data receiver. A synchro data receiver is a device which conv

A torque system is one in which the synchro data receivers are self-positioning without any servomechanism assist. Torque synchro data receivers are normally used to position pointers, di

22、als, or in other applications in which a low powered mechanical output is required. A control system is one in which the synchro data receivers are not self-positioning. They require a servomechanism to provide the required mechanical output. Since control synchro data receivers appear as high imped
