In this paper, a 12 - way high accuracy sine signal generator system based on FPGA is designed. The DDS signal source based on FPGA can not only output 12 - way sine wave signal, but also can regulate the frequency, phase and amplitude of output waveform by STM32 main control module. In this paper, the structure, working principle and logic circuit of 12 - way high accuracy sine signal generator system...
