摘要:频率的调制和解调是通信电子线路中非常重要且比较关键的一部分,调频电路在通信电子线路中运用非常广泛且作用很大,如何学好此部分对我们来说非常重要。本课程设计的内容是学习基于Multisim的调频电路设计与仿真。用Multisim仿真软件进行调频电路调频和解调,得到仿真结果。调制信号的仿真结果是弹簧波形图,解调信号的仿真结果是调制信号波形图。从仿真结果中更好地理解频率的调制和解调。 Abstract: frequency modulation and demodulation is a part of communication electronic circuit is very important and key, frequency modulation circuit is widely applied and plays a great role in the communication electronic circuit, how to learn this part is very important for us. The content of the curriculum design is the study of design and Simulati
on of frequency modulation circuit based on Multisim. FM frequency modulation and demodulation, using Multisim simulation software, the simulation results are obtained. Simulation of modulation signal is the result of spring waveform, simulation of signal demodulation results are modulated waveform. From the simulation results in better understanding of frequency modulation and demodulation.
