| Abstract: | It introduced several methods for generating sine wave Processor（DSP）. The main source programs of these methods were given, based on Digital Signal and the hardware circuit of interface between TMS320C5402 DSP and Digital to Analogue （D/A） inverter TLC320AD50C was given in the meantime. Then sine waves from simulation and emulation were also shown. At last, advantages and disadvantages of these methods were analyzed and adjusting frequency method was discussed. |
