Abstract
A synchronous oscillator demodulator for linear variable differential transformers and synchronous resolvers having electronic circuitry designed to digitally construct a preferred waveform of a predetermined frequency and to establish precisely the preset point at which the amplitude of the waveform is to be measured at the secondary winding of the transformer. This synchronous oscillator demodulator permits the use of linear variable differential transformers and synchronous resolvers for high frequency applications and under conditions of noise and vibration while still maintaining a high degree of accuracy and repeatability. A system and apparatus to enhance the signal from a given linear variable differential transformer and tune sane in relation to the signals of other similar but not identical transformers is disclosed.
