1. A signal processing circuit for removing a noise component from a detection signal of a yaw-rate sensor which detects a yaw rate generated in a motor vehicle, comprising:

  • means for obtaining a magnitude of variation of the detection signal of the yaw-rate sensor;

    comparison means for comparing the magnitude of variation of the detection signal with a predetermined reference value; and

    output means for outputting a limitation detection signal which limits the magnitude of variation to below said predetermined reference value when the magnitude of variation of the detection signal is determined to be greater than said predetermined reference value by the comparison means, and for generating a detection signal with its noise component removed based on the limitation detection signal.
