Digital Frequency Synthesis Using DDS-Based Approach

Abstract:

This paper deals with some issues during the synthesis of DF signals such as change of phase and sine amplitude, smooth output and wave filter which features dynamics and variability. Utilizing AD9833 chip, this paper design the circuit that is used for synthesizing DF signals, including external circuit, wave filter circuit and amplify circuit. Given the characteristics of this chip, this paper provides the procedure design methodology that includes AD9833 initiative, write control and synthesis frequency. The testing experiments indicate the accurateness and reliability of this design.
