本文介绍了在数字下变频(DDC) 中的抽取滤波器系统设计方法和具体实现方案。采用CIC 滤波器、HB 滤波器、FIR 滤波器三级级联的方式来降低采样率。通过实际验证,证明了设计的可行性(This article describes the digital down conversion (DDC) of the decimation filter system design methods and concrete realization of the program. Using CIC filter, HB filter, FIR filter cascade three-level approach to reduce the sampling rate. Through the actual authentication, to prove the feasibility of the design)

一种学习用的小程序，主要用与VHDL仿真的全加器的一段代码！大家可以下载进行修改于仿写-A learning to use a small program, mainly used with the VHDL simulation of a full-adder code! You can download the modified Yu Fang Xie

用游戏把子上下左右控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，不能咬到自己的身体，更不能咬自己的尾巴，等到了一定的分数，就能过关，然后继续玩下一关。
