Abstract
Many telecommunication applications require a fast switching, fine tuning and superior quality sinusoidal signal source for their components. One such a frequency synthesizer is a direct digital synthesizer (DDS). This thesis work utilizes a design that aims to combine digital circuit design and electronic communication knowledge, and apply them in a practical environment. It does so by providing a tutorial on designing and implementing a DDS on an FPGA using Xilinx’s ISE software. The thesis also examines the final results and shows the unwanted spurs that are generated. Since this is purely a digital design, it does not implement a digital-to-analog converter (DAC) or a low-pass filter. Using a Virtex 6 design for the FPGA, one can achieve close to perfect sinusoids, without any phase change, with varying frequency tuning words (FTWs).
