摘　　要：针对当前模拟电路和数字电路实验缺少统一完整的实验平台的问题,自主设计开发了满足电类和非电类专业实践教学要求的综合实验系统平台,系统包括电源、单管放大电路、运算放大电路、功率放大电路、脉冲电路、显示电路等实验模块,集模电、数电、单片机实验于一体,可独立可综合地展示不同电路的实验过程。主要设计了基于自主设计综合实验平台的扩音机小系统,实践表明综合实验系统激发了学生的实验实践热情,使学生了解和掌握了扩音机的原理、特点、实现方法、调试方法等,加深了学生对模拟电路知识的理解。In view of the lack of unified and complete experimental platforms for the current analog circuit and digital circuit experiments,a comprehensive experimental platform is independently designed and developed to meet the practical teaching requirements of electrical and non-electrical majors.The system includes power supply,single tube amplifier circuit,operational amplifier circuit,power amplifier circuit,pulse circuit,display circuit and other experimental modules.The self-designed platform includes analog circuit,digital circuit and single-chip microcomputer experiments,which can independently and comprehensively display different the experimental process.A small system of amplifier based on self-designed comprehensive experimental platform is designed.Practice shows that the system stimulates experimental enthusiasm and interests of students.Students can better understand and master the principles,characteristics,implementation methods and debugging methods of amplifiers,which deepens their understanding of analog circuit knowledge.
