【正文】 an important role in all fields. The munication system design needs to make the simulation first, in order to improve the availability of the system. Dynamic Simulation Software System View, it can be used for constructing a variety of plex analog, digital, mixed munication systems and various multirate system, and also can be used for a variety of linear or nonlinear control system design and simulation. It is a powerful tool for dynamic system analysis, including digital signal processing (DSP), analog and digital munication systems, and signal processing system and control system simulation analysis. According to a modular and interactive interface, under the Window in the Windows environment, System View provides users with an embedded analytical engine. System View is a tool of programming for circuit and munication system design, simulation of dynamic analysis. It avoids the plex hardware structures. On the conditions that don’t have the advanced equipment, it also can plete a plex munication system design and simulation. True Software Design System view this thesis, analog modulation and demodulation circuit. By analyzing the input and output waveforms of the correctness of the circuit design. The thesis mainly including an overview of munications systems, analog munications system and the basic contents and use System View, simulation software simulation of munication systems to achieve the simulation. Analog munication systems are the main elements of the basic munication system model, the linear analog signal modulation (AM,DSB,SSB) and demodulator, nonlinear modulation(FM,NBFM) and demodulator, the thesis also give a brief introduction on the simulation software(System View), while using simulation software to achieve the simulation of the munications system simulation.
