Abstract:

This article describes the basic operating principle of the signal generator and the design process based on the direct frequency synthesis technology DDS.With MCU and FPGA as the core of the design,we implement a source generator which can adjust the waveform,the frequency and the amplitude.Simulation results show that the proposed generator achieves desirable results and meets the design requirements.

Key words: MCU;FPGA;DDS;signal source
