FPGA based Phase Demodulator

FPGA based Phase Demodulator


Features :

  • This system will receive two out of phase signals from the gyroscope
  • Modulating signal of 0-100Hz, 1V p-p
  • Carrier signal of 200KHz
  • The output is the phase difference between the signals with amplitude (0-20)V p-p
  • System implements following programs in VHDL :

      Hilbert transform

      Complex multiplier

      FIR filter
