基于FPGA的变频脉冲信号周期检测系统的设计

Design of Non Fixed Frequency Pulse Period Measurement System base on FPGA

简单介绍了一种变频脉冲信号的周期检测方法,详细介绍了一种变频脉冲信号周期检测系统的设计方案,通过FPGA予以了实现,并给出了部分VHDL程序设计思路和仿真波形。实验结果表明,所述系统的设计方案合理可行,系统检测出的信号可参与和周期信号有关的各种计算。

In this paper,a measurement way of non fixed frequency pulse period is introduced. A design way of non fixed frequency pulse period measurement system is discussed in detail. The system is achieved by FPGA,and the partial VHDL idea and simulation waveform is given. Test results indicated that the signal which is generated by the system can be used in calculation.
