Abstract

The paper considers the design and modeling of digital frequency synthesizer with a filtration of generated wave. As filter element were used 6 order elliptic filters. The simulation allowed to develop and research the experimental model based on modern digital frequency synthesis device. The simulation results confirm the efficiency of the proposed circuit for improve the amplitude frequency characteristic of synthesized signal and the possibility of using modern digital synthesis device as a variable-frequency oscillator in the radio-technical devices.
