频率计是一种对信号的频率进行测量的仪器，是一种典型的电子测量仪器。能对频率量进行测量的仪器有许多：如模拟频率表、示波器、数字频率计、微机化智能频率计等。本文将对数字频率计项目进行探讨并设计和制作。
Frequency counter is a signal frequency measuring instruments, is a typical electronic measuring instruments. On the frequency of volume measuring instruments have many: such as analog frequency table, oscilloscopes, digital frequency meter, frequency meter microcomputer, such as intelligent. In this paper, digital frequency meter project will be carried out to explore and design and production. (2007-07-26, HTML, 49KB, 下载17次)
