基于乘法器调幅电路设计与仿真
资料介绍
高频电子技术中，调制信号的实现和波形的频谱分析是难点。根据调幅电路的理论知识，直观地用乘法器来实现信号的调幅，通过设置不同的输入信号来实现信号的正常调幅和平衡调幅。并通过示波器观察不同情况下调制后的信号波形，通过Multisim提供的傅里叶分析功能分析调制信号的频谱图，实现对电路进行仿真分析。仿真结果表明，利用乘法器能实现信号的调幅。
The realization of modulation signal and spectrum analysis is difficult in high frequency electronic technology. According to the theory of amplitude modulation circuit,visually using multiplier to realize signal amplitude modulation,by setting the different input signal achieve normal amplitude modulation and Balance amplitude modulation.And through the oscilloscope observe modulated signal waveform,of the different situations, Fourier analysis function provided by Multisim analysis of the modulation signal spectrum, simulation analysis was carried out on the circuit. The simulation results show that using multiplier can realize signal amplitude modulation.
