Based on the current situation of the national first-class curriculum construction of the course of Signals and Systems, combined with the needs of the construction of the national virtual teaching and research section, we construct the system structure and specific content of multi-digital teaching resources based on BOPPPS teaching mode, which provides reference for teachers to carry out curriculum teaching, and provides guiding learning for students and social learning groups to carry out independent learning.
