摘要
针对目前使用的高频实验箱存在的诸多问题,设计了一种新型高频电子线路实验系统。该系统采用了模块化设计的方法,共分为九个模块,分别为小信号谐振放大器、丙类功率放大器、混频器、调幅振荡器、检波器、调频和振荡电路、鉴频器、遥控编码电路以及遥控解码电路。九个模块既可以独立开展实验,也可以相互连接,开展六个以上的综合实验。本实验系统紧扣实验教学大纲,在满足基本验证性实验的基础上,大大扩展了设计性和综合性实验内容。
Considering the high frequency circuit experiment box at present having many defects,a novel experiment system is designed.Modularity method is adopted in this system,which contains nine module circuits.These circuits include small-signal resonance oscillation amplifier,C-class power amplifier,mixer,amplitude modulation,demodulator,frequency modulation and oscillator,frequency discriminator,remote control coding and remote control decoding.The nine modules can carry out experi ment independently as well as contact each other to develop synthetical experiments more than six.Based on satisfying the basic verifiability experiments,teaching outline is clenched by this system,which extends developable and synthetical experiment great ly.
