signal-processing
- 自己制作的信号生成与信息处理模块，对生成的信号进行滤波，采样FFT然后分析功率谱,输出高通信号-Signal generation and produce their own information processing module, a signal generated by filtering, sampling FFT and then analyzes the power spectrum of the output high communication No.
Median-filter-
- 在信号处理中，它通常是可取的是能够执行某种降噪图像或信号。中值滤波是一种非线性数字滤波技术，通常用于去除噪声。这种噪声是一个典型的前处理步骤，提高后处理的结果（例如，边缘检测在图像）。中值滤波是非常广泛的应用在数字图像处理中，在一定的条件下，它保留了边缘，去除噪声-In signal processing, it is often desirable to be able to perform some kind of noise reduction on an image or signal.
