  • Abstract
    A CARRIER-CONTROLLED RELAY servo system is one in which a carrier voltage is supplied to the system, along with the signal, to control the transmission characteristics of the relay. The most familiar example of carrier-controlled operation is the self-oscillating relay servo, in which the carrier is supplied internally by the self-oscillations. However, the practice of supplying carriers from external generators for this purpose has grown rapidly over the last ten years.
