Title:
TRANSMITTING APPARATUS
Document Type and Number:
Japanese Patent JPS54109859
Kind Code:
A
Abstract:
A synchro transmitter having a rotor driven by a compass communicates the heading information from that compass to a plurality of loads via respective synchro receivers whose rotors are energized with direct current or carry permanent magnets and whose stators are supplied with a triad of d-c signals from three modular units each having one input connected to an output lead of a respective stator winding of the transmitter and another input connected in parallel with a winding on the transmitter rotor to a source of alternating current. A demodulator in each unit compares the current of the respective output lead with the reference current from the a-c source and feeds the result to an integrating operational amplifier which emits the corresponding d-c signal.
