“…In the background of the construction of new engineering, based on the shortage of traditional practical teaching courses, actively explore interdisciplinary and interdisciplinary teaching cases, introduce the exciting practical projects in electronic thematic design competitions into the electronic technology course design, link the knowledge points in circuit analysis, digital electricity and analog electricity efficiently, emphasize the connection between theory and practice, lay a solid foundation for students to master more complex and systematic circuits in the future It also aims to improve students' awareness and ability of independent analysis, judgment and problem solving, and to deliver applied talents who can solve complex engineering problems for socialist construction [5] . Take the cases in the electronic thematic design competition in the past four years as an example, the cases are from the hands of top experts in circuit design, as shown below, the cases perfectly integrate the rectifier, filter, voltage regulator, counter, register, latch, operational amplifier, waveform generator, combinational logic control and other circuits in the courses of circuit analysis, digital electricity and analog electricity, which opens up the traditional practical course knowledge points in the "silo", guide students to learn actively and develop their ability to synthesize the knowledge they have learned and solve practical and complex engineering problems.…”
