摘　　要：在物理专业"模拟电路实验"课程的教学中,培养学生学以致用的能力是现代教学活动中不可缺少的目标。2.1声道中功率放大器,是一种普及率很高的高保真放大器,该放大器的电路设计选型、组装调试,直接影响到该功率放大器的高保真效果,作者以TDA2030集成功放为基础,介绍了2.1声道中功率放大器的电路设计选型、PCB电路布线进行的各种优化。完工后的产品经试听、测试,各项性能指标达到国家视听标准,全过程完全适用于理科学生由单一实验向工程转型的综合研究性实验教学。In the teaching of the course ＂analog circuit experiments＂, it is an essential objective in modern teaching prograin to cultivate students＇ ability to learn to meet practical needs. The 2.1-channel power amplifier is a hi-fi one with a high popularity whose selection of circuit design, assembly and trial operation directly affect the hi-fi efficiency of this kind of power amplifier. On the basis of the TDA2030 integrated power amplifier, this paper discusses the selection of circuit design of 2.1-channal power amplifier, the optimized eireuits for PCB wiring, perfomlance indexes for national audiovisual requirements and its feasibility of applying the whole process to the experimental teaching.
