Design of Multi-channel DDS Signal Generator Based on FPGA

Wenqiang Zheng

Open publisher page 1 citations

Abstract

A method based on FPGA was presented for multi-channel DDS signal generator.With output high-accuracy D/A converter for core waveform reconstruction electrical,the signal is achieved by electronic analog switch.In this design,the signal generator can provide four waves,which included sine wave,sawtooth wave,triangle wave and square wave.The frequency,amplitude and offset of the signal are flexible and adjustable.
