The DSP application technology is a comprehensive course, occupies an important position in the personnel training programme of electronic information engineering. In order to improve students' learning enthusiasm and comprehensive ability, a problem oriented project-based teaching model is proposed to reform and explore the teaching methods, teaching content, and assessment of the curriculum. In order to meet the needs of different students, two experimental projects with varying levels of difficulty are designed, and students can choose a project based on their abilities. The entire teaching process is student-centered, with teachers providing guidance throughout the entire process. This model creates problem scenarios for students, fosters an environment for independent exploration, effectively enhances students' problem-solving abilities, and significantly contributes to students comprehensive understanding of DSP-related knowledge.
