| Abstract: | The Paper designs the kinds of the signal generators based on direct digital frequency synthesize(DDS).The system produces a machine order control word and a code dollar by SPCE061A single chip,the sinusoidal and FM signal by AD9850,and realizes a distance of ma control and ASK/PSK single by the imitate switch SPCE061A.The system has the characteristic of a distortion degree of the signal is small,the frequency extension is big and stable etc. |
