A Signal Generator Based on AD9850

Abstract:

This paper analyzes the advantages of the direct digital frequency synthesis (DDS) in signal generator applications, introduces the basic principles and characteristics of AD9850, a cost-effective chip, shows the overall scheme of a signal source design based on DDS and implements the hardware system. Experimental results show the signal generator can produce sine wave signals scoping from 100Hz to 5MHz, clock signals and triangular wave signals and can display frequency on the LCD.
