Design of real-time control harmonic generator based on FPGA

In order to solve the problems of large volume and poor portability of traditional signal generators, this paper uses Xilinx AX7050 FPGA(Field Programmable Gate Array) and AN108 AD/DA converter to design a signal generator that can be controlled in real time. The generator can operate independently from PC(Personal Computer) terminal, and can generate arbitrary waveform with adjustable amplitude, frequency and phase. After comparison with matlab simulation waveform, the output waveform of the signal generator has the advantages of stable frequency and high precision.
