Abstract：Based on direct digital frequency synthesis （DDS） technology， a multi signal generation system is designed in this paper. The system can generate continuous wave， linear frequency modulation signal， pulse modulation signal and design PC control software based on MFC framework. The test results show that the system is simple in structure and flexible in configuration， which is of practical significance to the design and implementation of signal source.
