Abstract

This paper aims to design and implement a digital-analog hybrid transmission device based on STM 32 to realize the synchronous transmission and processing of analog and digital signals. Firstly, this paper briefly describes the basic concepts and characteristics of analog and digital signals, and clarifies the necessity and application scenarios of digital-analog hybrid transmission. Subsequently, according to the design tasks and requirements, the overall scheme design was formulated, and the feasibility of the scheme was demonstrated in detail. In the design process of the device, the STM 32 microcontroller is adopted as the core control unit, combined with the analog signal conditioning circuit and the digital signal processing module, to realize the signal acquisition, conversion, transmission and processing. The reliability and stability of the device were verified through physical production and testing, and it was optimized and debugged. The research results of this paper not only provide an effective solution for the transmission of digital-analog hybrid signals, but also provide a reference for the research and application in related fields.
