Abstract
A position transducer with a variable transformer and a feedback transformer to which an a.c. signal is applied via a variable gain amplifier controlled by the integrated output of a phase-sensitive rectifier. The secondary of the feedback transformer is connected in series with the primary of a coupling transformer coupling the variable transformer to the rectifier and with the secondary of the variable transformer so that in equilibrium there is a null voltage across the primary of this coupling transformer.
