Principle of Narrow Band Frequency Modulation and Its SystemView Simulation

Xueya Zhang

Abstract

SystemView is one kind of Electronic Design Automation(EDA) software,it has been widely used because its formidable function in the communication simulation.Taking the Narrow Band Frequency Modulation(NBFM)as an example,the process of communication question solution by EDA technology is given.NBFM modulation and demodulation principle are discussed.Using Systemview Software to build Simulation Model on the basis of principle diagram.The characteristics of NBFM signal and the anti-noise performance of different demodulation methods are analysed.
