ABSTRACT:
A circuit for overcoming variations in the output signals from a synchro device resulting from a.c. supply voltage variations includes means to provide a pulse train in which the pulse widths are modulated in accordance with supply voltage variations. A signal derived from a pair of synchro output terminals is applied to a rectifier/filter which is intermittently actuated by the pulse width modulated signal. The resultant d.c. signal is effectively divided by a factor proportional to the supply voltage so as to be independent of variations in that voltage.
