Direct Digital Synthesizer using Numerically Controlled Oscillator for Signal Generation

Arti Dattatray Gaikwad, Shekhar H. Bodake

The Direct Digital Synthesizer is implemented with the numerically Controlled Oscillator. The Direct Digital Synthesis is an advanced method of producing analogue waveforms where the generation is done completely in the digital sphere. This paper presents a design for a Direct Digital Synthesizer (DDS) which generates multiple waveforms. The proposed NCO is based on a 32 bit phase accumulator and a 12 bit addressed look-up table (LUT) as phase to amplitude converter. This design will be simulated in Xilinx12.3. This DDS will offer qualities like fast switching, good frequency resolution and good stability. This DDS can become highly convenient if it is designed on a Field Programmable Gate Array (FPGA). A FPGA-based system requires less development cycle and reduced space for design also increase the performance.

Keywords: NCO, DDS, LUT, Xilinx, Phase accumulator
