Tan Yong-hong · Ceshi jishu xuebao · 2008
A complete synchronization digital frequency meter is designed using FPGA chip by VHDL language programming according to the complete synchronization measurement theory.It eliminates ±1 count error with an accurate frequency-measuring range of DC~100 MHz.This paper gives the design approach by VHDL and the simulation waveform of every module of the meter.A system board can be made with the FPGA chip,which has higher practicability and reliability.
