摘要
文章简要介绍调制解调原理,结合无线电罗盘的检波电路,分析了罗盘的调幅检波。文中围绕器件CA3070着重叙述相干解调的原理及过程,同时使用仿真软件Multisim对解调的电路进行仿真。
This paper briefly introduced the modulation and demodulation principle,combined with the detection circuit of radio compass, it analyzed the modulation and detection of the compass. This paper mainly described the principle and process of coherent demodulation around the device CA3070, and simulate the demodulated circuit with the simulation software Multisim.
