【Abstract】 In order to better carry out the experiment teaching of communication electronic circuit, a communication electronic circuit experimental box based on communication system is designed. The experimental box can realize the functions of short-wave AM radio, short-wave AM transmitter, wireless communication of transceiver, and frequency modulation and discrimination system. The design idea, system scheme and hardware design are introduced in detail, as well as the arrangement and teaching effect of practical experiment teaching. The experiment box can be used not only in conventional teaching, but also in project teaching. It is suitable for popularization in experiment teaching.更多还原
