WebMay 16, 2024 · In the context of the LVDT signal conditioning, a demodulator is the circuit that converts the AC output of the LVDT to a DC signal whose amplitude and polarity reveals the core position. Rectification-based demodulators and synchronous demodulators are the two main options that can be used with an LVDT device. Webbridge rectifier. The ripple components are minimized by the use of LC filter. The ripple-free high voltage DC is fed to a colpitt's oscillator. The oscillator circuit produces high frequency power and feeds it to the input of an inductive coil which is the primary of the work coil. The work piece acts like a short-circuited secondaiy.
