In this design, a single-phase exciting signal gener AT ed by RC oscill AT ory circuit is applied to the rotor of synchro. The sine and cosine signals induced on st AT or are amplified by instrument AT ion amplifier and connected to the converter AD2S83, which is designed according to tracking goniometry. Digital logic control and address encoding are processed by FPGA , and the converted 16-bit parallel angle d AT a and direction signal are transferred to DSP.
