摘要
文章阐述了窄带调频信号调制与解调的数学模型,建立了系统原理图,并运用通信仿真软件SystemView对其电路模型进行了设计。从功率谱、时域波形等方面对电路模型进行了仿真研究,基于仿真结果从矢量角度对窄带调频信号进行了分析,其仿真结果与理论一致。
It is described that modulation and demodulation mathematical model of the Narrow Band Frequency Modulation （ NBFM）signal and system elementary diagram is established. The system circuit simulation model is designed by using SystemView software of the communication. The model is simulated from power spectra and time domain waveform and the result is analysed from vector. It is demonstrated that simulation results agreed to theory.
