According to the system bandwidth, the low pass filter was added in controller to assure the tracking effect of system and filter the super-high frequency in control singles.
根据系统的带宽，在控制器中加入低通滤波器，以保证系统跟踪效果，过滤控制信号中频率过高部分。
Since the Fourier transform of a Gaussian is another Gaussian, applying a Gaussian blur has the effect of reducing the image's high-frequency components; a Gaussian blur is thus a low pass filter.
由于高斯分布的傅里叶变换仍然是高斯分布，使用高斯模糊就减少了图像的高频分量，因此高斯模糊是低通滤波器。
