Signal source is an important part of modern electronic system and has a wide range of applications in the fields of communication, measuring & control, navigation and medical care. This project developed a new dual-channel sine wave generator with Tunable Phase Difference on the basis of the direct digital frequency synthesis (DDS) technology. Design was accomplished using STC89C52 MCU and FPGA as the control center, integrating basic operation circuit and employing low-pass filter and the necessary software algorithm. The experimental results showed that the system can produce dual sine waves with tunable phase difference in 0~359° range. The system is stable in work and it is easy to adjust parameters.
