摘　　要：电路综合实验是电子信息类专业必修的一门专业基础实验课,在课程衔接上起着承上启下的重要作用。分析了通信专业学生不同学习阶段的专业知识层次特点,提出用模块化的设计理念,并以此理念为指导,以数字基带传输系统为例,利用FPGA（field programmable gate array）技术,将软件仿真和硬件结合起来,解决了数字基带传输系统设计环节中几个关键的技术问题,开发了各个模块级实验以及整个系统级实验,实现了不同阶段课程内容的有效衔接和融合,解决了学生知识背景低和实验内容层次高的矛盾。The circuit synthesis experiment is a compulsory professional basic course of electronic information engineering,and it plays an impotant role of connecting in the course convergence.This article analyses the professional knowledge hiberarchy character of the students majoring in communication engineering in different learning stage,and introduces the modular design concept.Based on this concept,the digital baseband transmission system is provided by using the FPGA technology,several key technical issues are solved,and every modular experiment and the entire systematic experiment are developed.These experiments connect the software simulation and the hardware implement together,and solve the inconsistency of the short of students＇ background knowledge and high level contents of the experiments.
