摘要
介绍了运用FPGA技术产生的调幅调频信号的方法,设计中采用直流数字式频率合成器(DDS)和全数字锁相环结合的理论。给出了用VHDL实现了调幅调频信号的设计方案和具体实现方法。该设计的性价比在可调制信号发生装置中优于其它的设计,具有一定的实用性和使用价值。
This paper introduces the method producing AM signal and FM signal by FPGA technology.It uses the theory that combines the direct digital synthesizer device（DDS） and the phase- locked loop in its design.The paper presents the design project and the realization of concrete achievement of AM and FM.Compared with other designs,the performance price ratio of the method has advan- tage in modulated signal device and possess certain practicability and usefulness.
