A kind of phase shifting sine wave generator based on DSP digital oscillator is designed. The system is consisted of TMS320VC5416 minimum system and two TLC320ADSOC chips and simple peripheral circuits. The system software and hardware design are introduced briefly in this paper. Two predefined phase shifting sine waves can be obtained by DSP digital oscillator technology and the design objective was fulfilled. The experimental results show that the system has the characteristics of simple structure,convenience and ...
