| Abstract: | The kind of frequency measurement technique which adopts a new method of equal-precision is introduced and improved. The solution is provided using FPGA. The main parts are programmed by applying VHDL hardware language and Max＋plus Ⅱ software. Some discussions are also made for the error. The precision of measurement is improved by utilizing the characteristics of shorter delay of internal gates and more stabile circuit in FPGA. |
