Based on the digital frequency synthesis technology,the digital sine wave is generated by modular design and look-up table method. The direct digital frequency synthesis technology,as a kind of advanced circuit structure,can output in full digital signal frequency. So it is much better than the analog signal generator in precision and flexibility. In the circumstances,Quartus II,with very-high-speed integrated circuit hardware description language,the modular design is conducted by programming.EP1K30TC144-3...
