Abstract : The patent relates to analog output signals from a synchro stator winding converted to binary form by gating each analog signal with a relatively high frequency square wave which is shifted in phase by an amount equal to the physical phase displacement of its associated stator winding. These signals are then summed, filtered and limited to form a signal which is phase shifted in proportion to the synchro shaft angle. Comparing this phase shifted signal with a fixed reference signal provides a gated signal with pulse widths proportional to synchro angle. These pulses may then be converted to a binary signal containing angular information.
