DDesign About Circuit For Modulated Signal of FPGA
Hen Y · 2007
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 re- alization 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.
