Abstract :
In addition to the traditional analog filter circuit, an intelligent filter chip MAX260 that can track signals with a certain frequency, and keep their amplitude and phase constant but attenuate signals with other frequencies as the microchip controller part´s filter is added after the pre-processing circuit. Combining MAX260 and digital filtering arithmetic, the anti-disturbance of the conditioning system is improved greatly.
