Open publisher page 0 citations

Abstract

This paper presents an arbitrary waveform generator based on DDS.Under the control of the MCU and FPGA,the data has been stored in the RAM of FPGA will be took out in certain order,and then analog waveform will be exported through D/A converter.This method makes full use of the FPGA's internal hardware resources,and greatly improves accuracy and frequency range of the waveform.
