多信号的合成信号发生器系统设计

信号发生器是一类十分重要的仪器,在通信、测控、导航、雷达、医疗等领域有着广泛的应用。考虑到性价比我们选择了一款扩展功能的51系列单片机W78E58作为本仪器的处理器。信号产生的核心芯片选用AD公司的AD9852。该信号发生器具有输出信号波形种类多、精度高、频带宽等特点。

Signal generator is very important in morden electronic instruments.It is widely applied in many field such as conmunitication,navigation,radar measure and control.Consider cost performance we choose one 51 serial MCU W78E58 of expanded function,as processor of instrument this.The key chip that the signal produces selects AD9852 of AD Company.The signal generator has many virtues,such as generating multiple sorts of signals,high precision and wide frequency width.
