Design and Implementation of DDS Module on FPGA

The paper concerns the construction scheme of Direct Digital Synthesis (DDS) generator based on widely developed Field Programmable Gate Arrays (FPGA) technology. based on (DDS) it generates sine wave that frequency and phase is manageable is designed with direct digital synthesis(DDS) technology. It is showed that the design based on FPGA with DDS is dependable and practicable. The output wave by test reaches the essential aims, easy control and high performance. The DDS produce sinusoidal signal owns the features of modest circuit, easy to be measured, unchanging performance, high frequency conversion speed and fine accuracy etc. And its output frequency falls within the range of 0Hz ~ 150KHz with 5 Hz of steps
