LVDT signal conditioning

LVDT transformer by a fixed frequency sine wave to excite. The displacement distance of the movable core will change the amplitude of the output transformer, which is true by the LT1967 RMS converter is converted to a DC voltage. Shifted to the direction of movement of the core is indicated by the phase of the sine wave, and using  a simple comparator circuit to detect a phase.
