Abstract:How to extract the differential signal in noise pollution signal is discussed in this article. Firstly, the mathematical meaning of the classic differentiator, and the cause of the noise amplification is analyzed. Based on the theory of steepest trackingdifferentiator, the phase delay compensation is forecasted and the frequency characteristic is analyzed. Then the steepest tracking differentiator in the line of sight acceleration is simulated and analyzed.
