数字频率计
该项目用来测量频率。它有三个范围,其中包括 0.01 赫兹 ~ 1 Hz,1 ~ 100 Hz 和 100 ~ 10000 Hz。这样的结果将是最好的程序能自动调节到最佳的范围内。这个项目是在 Altera 软件 8.1 上进行验证。

由于在网上很难下载到EDA技术-窦衡的PPT,所以本人经过学习后做成word,供大家下载。只针对VHDL语言部分和所有的程序。-Because the Internet is difficult to download to EDA technology- Douheng of the PPT, so I made after learning after the word, for all to download. Only for part of the VHDL language and all the procedures.
