Abstract
】
This paper first introduces the development of signal generator and the current situation and development trend of DDS, and then introduces the working principle and main structure of DDS. According to the requirements of the subject, DDS technology is adopted as the core technology, and a function signal generator with simple structure and excellent performance is designed with the chip STC15W4K32S4 and AD9833 as the core. The circuit and interface design of each module and the s
