Design and research of intelligent signal generator

Abstract The intelligent signal generator is a key device widely used in the fields of communication and electronic measurement. This paper addresses the issues of single functionality and complex operation of existing intelligent signal generators and proposes a design scheme for an intelligent signal generator based on the STM32F407 processor. First, the functional requirements of the intelligent signal generator were analyzed to determine the main technical specifications of the system. Second, a design based on the STM32F407 core control board and a multifunctional signal board was developed, enabling programmable control of parameters such as frequency, amplitude, and waveform of the intelligent signal generator. Third, high-precision generation of multiple waveforms (such as sine waves, square waves, and triangular waves) through multiple pathways was achieved. Finally, experiments verified that the designed intelligent signal generator has high performance and good stability. The research results of this paper provide new ideas for the design of intelligent signal generators and have certain theoretical value and practical application prospects.
