您要查找的是不是：
- RC filter circuit is used to filter the sensor signal, then demarcate the filter signal, and fix on linear curve by regression equations. 采用RC滤波电路对检测传感器信号进行了滤波，然后对滤波后的信号进行了标定，通过回归方程确定出线性关系曲线；
- In the receiver, the Kalman filter is used to reduce the noise interference.Then the filtered signals are demodulated by chaotic demodulation. 本文从抑制噪声干扰的角度出发,在接收端先使用卡尔曼滤波器对接收到的信号进行滤波处理,以降低噪声对混沌信号的影响,然后进行相应的混沌解调。
- Another applied in filtering signal containing Gaussian white noise is computed directly by utilizing time-frequency spectrum of GST, which can enhance non-stationary signal and suppress noise. 后者直接应用广义S变换的时频谱实现，用于含高斯白噪声信号的滤波，达到了突出有效信号和压制噪声的效果。
