  • Signal conditioning system with a sigma-delta modulator
    Publication number: 20110279162
    Abstract: A signal conditioning system includes a first filter, a signal processing module connected with the first filter, a second filter connected with the signal processing module, and a ?-? modulator connected with the second filter. The signal processing module makes the saturation overflow treatment to the signal output by the first filter using the characteristics of the radix complement adder. The ?-? modulator is a high order filter formed by a plurality of cascaded and inter-stage feedback second-order filters. Based on the performance of the ?-? modulator and the whole system, the stability of the signal conditioning system is improved.
