For the problem of high precision frequency measurement of dynamic signals with high fundamental frequency and small frequency change value in electronic measurement, a method of differential frequency measurement is introduced. A novel dynamic adjustable multi-stage frequency-difference circuit structure is proposed. The fast differential frequency measurement system based on FPGA is used to design the Fast Fourier Transform (FFT) algorithm on the FPGA to realize the data processing function of the system. The simulation and experimental results show that the structure of the multi-stage differential frequency circuit can be designed with high precision frequency, and the result can be obtained when the spectrum analysis is carried out. The system can realize the fast FFT operation. Compared with the MATLAB software platform, the system has obvious advantages in the efficiency of data processing. The structure of the FFT model can be dynamically adjusted to meet the requirements of FFT operation of different scale points, and the system performance index can meet the requirements of data acquisition system.
