| Abstract: | This paper introduces a two-channel sine wave supply based on digital wave syntheses and designed by MCU and FPGA.The output frequency and phase-difference of the two-channel can be programmed separately with 0.1Hz and 0.1? resolution.The circuit has the functions of high frequency precision and stability and low wave distortion which can be used as a standard wave supply in high precision system such as electric power meter calibrating. |
