Research of digital signal processing based on system learning model

Abstract

Undergraduates majoring in information science usually offer compulsory or elective courses in signal processing, while digital signal processing courses are both theoretically and practically strong. According to the learning objectives of undergraduates in universities, the author introduces the digital signal processing in the background of the development of modern information field, this paper puts forward a practice learning method oriented to system of thinking and engineering mode of ability cultivation, which can improve traditional learning of theory and practice and has reference significance for agricultural colleges to enhance the professional foundation of information students.
