- 运用等精度测量原理,结合单片机技术设计了一种数字式频率计,由干采用了屏蔽驱动电路及数字均值滤波等技术措施,因而能在较宽的频率范围和幅度范围内对频率、周期、脉宽、占空比等参数进行测量并可通过调整闸门时间预置测量精度。-The use of other precision measuring principle in combination with single chip technology to design a digital frequency meter, shielded from t
3_3_mean_diltter(ALU)
- 3*3均值滤波的VHDL语言实现的工程,对红外图像进行有效的去噪处理。这是其中的ALU模块,专门用来测试其延迟状况的模块。-3* 3 mean filter VHDL language works effectively on the infrared image denoising. This is one of the ALU module, designed to test the status of the module delay.

- 本实验完成加权均值滤波,其原理如下: 设采集到的数据按节拍输入,依次表示为d0,d1,d2,d3,d4,…,则输出依次为 do= d0*1/4+d1*1/2+d2*1/4 do= d1*1/4+d2*1/2+d3*1/4 … 假设采集到的数据为8位unsigned,输出do只保留整数。-This experiment is completed weighted mean filter, which works as follows: Set data collected
