验证性实验是通信工程专业实验课程的一个重要组成部分，简单易操作，但常因技术含量不高而不被重视。 实际上结合PBL问题教学法，只要对验证性实验进行合理的设计和有效的组织，虽不能像综合设计实验那样，能够直接提高学 生的设计能力和创新能力，但可以巩固通信基础理论，而且通过实验箱测得的信号都是实际信号，某种程度上还可以更好地验 证了通信系统的工程特性，对基础理论进行相对真实的模拟。

The verification experiment is an important part of the experimental course of communication engineering, which is easy to operate, but it is often ignored because of the low technical content. In fact, if we give a reasonable design and effective organization of the verification experiment, combined with PBL teaching method of problem, it not only can consolidate the communication theory, but also can verify the engineering characteristics of the communication system because the signal measured by the experimental box is an actual signal.
