基于AT89C52单片机简易频率计的设计要求如下：
(1)测量范围。幅度：0.5～5V；频率:1Hz~1MHz.
(2)测试误差≤0.1 。
(3)用4位数码管显示。当频率变化时，能通过数码管及时看到变化后的信号频率。
-Based on AT89C52 simple frequency count of the design requirements are as follows: (1) measuring range. Range: 0.5 ~ 5V Frequency: 1Hz ~ 1MHz. (2) test error ≤ 0.1 . (3) with 4 digital display. When the frequency changes, changes in time to see through the digital signal after the frequency.
