摘要
利用等精度测量原理 ,通过 F PGA运用 VHDL 编程设计一个数字式频率计 ,精度范围在 DC～ 10 0 MHz,给出实现代码和仿真波形。设计具有较高的实用性和可靠性。
A digital frequency meter is designed by using equal precision measurement theory, pass FPGA and program project on VHDL in this paper The frequency meter′ precision extension is DC^100 MHz The paper give realization code and simulation waveform, the system have upper practicability and dependability
