Abstract :
In this paper, we introduce the principle of the direct digital frequency synthesis (DDS) technology. Then the design scheme of sine signal source with the double channels of frequency division is presented based on EP2C5 produced by ALTERA. The conclusions drawn from the experimental results show that the output of the double channels sine signal source have characteristics of small waveform distortion, frequency accuracy. In addition, the frequency and the coefficient of frequency division are adjustable in real time.
