基于单片机的数字频率计的设计

Design of Digital Cymometer Based on Single Chip Microcomputer

针对传统频率计运行速度慢,测量范围低的缺点,本文提出了一种能测量高频率的数字频率计的设计方法。采用单片机作为电路的控制系统,主要介绍了备模块电路的构成原理和测频方法,并进行了相应的软硬件设计。用单片机作为控制电路的数宇频率计,测量频率的范围能够得到有效的提高。

For the slower rate and less measuring range of the traditional cymometer ,this paper proposes a high frequency which can be measured the design method of digital cymometer,lt is adopted the single chip computer as the control circuit,It mainly introduces the composition of each module circuit principle and frequency measurement method.And it has the corresponding software and hardware design. With the single chip microcomputer as the control circuit of the digital cymometer, the range of frequency measurement can be effectively improved.
