| Abstract: | The way is used which combines the Direct Digital Synthesizer(DDS) and Main Computational Unit(MCU) to design a function signal generator.It uses AD9850 as Frequency Synthesizer and it uses AT89S52 MCU as a core which can realize process control and task assignment.The generator can establish signal frequency and amplitude in advance.The stable parameter is better than 10-6.The principle and system components of DDS is introduced.It also introduces the methods which design the hardware circuit and software.... |
