Journal: Control Engineering of China
Keyword: DDS; AD7008; MSP430F435; signal generator;
Abstract: The basic theory of DDS,the function of chip AD7008 and the way of using of MSP430F435 are introduced.The theory and struc- ture of digital signal generator making up of MSP430F435 and AD7008 are given.The higher quality and lower cost of digital signal generator is produced using phase accumulator direct digital synthesizer technology.It is provided stability and low distortion,frequency modulation, phase medulation and amplitude modulation sine and cosine signal through digital modulation and signal processed by amplifier and filter.The source has high precision and stably frequency,and it provides high quality digital signal of source and convenience for high precision measure- ment and easily controlled.It has been proven to provide benefits to our practice application.
