| Abstract: | Adopting the reactive circuit of twice harmonic to process the sensor signal, the system is closed loop. The circuit of stimulating magnetis .m and signal processing are included in the circuit of fluxgate. According to the outputting trait of fluxgate detector and function of circuit, band-pass amplifier, phase-sensitive detector, integral filter, and feedback part form the circuit. Exciting magnetism, multi-band, band-pass amplifier, phase-sensitive detector, the part of integral and feedback and compensation of temperature and so on comprise the design of circuit. |
