Design of High Precision Frequency Measuring System Based on CPLD
Author(s): 
Pages: 19-22
Year: Issue:  4
Journal: Ocean Technology

Abstract: 介绍了等精度频率测量原理,对测量误差进行了分析.在6000m高精度CTD剖面仪数据采集系统设计中,采用单片机结合Altera公司EPM1270T144C5型CPLD实现系统功能,CPLD基于QuartusII软件平台开发,采用模块化设计方法,实现多通道频率信号等精度同步测量.通过海上的多次现场比测试验,验证了系统的可靠性.
