En FPGA implementering av en digital FM modulator. (Swedish)
Abstract [en]

The increase in speed and density of programmable logic devices such as Field Programmable Gate Arrays (FPGA) enables ever more complex designs to be constructed within a short time frame. The flexibility of a programmable device eases the integration of a design with a wide variety of components on a single chip. Since Frequency Modulation (FM) is an analog modulation scheme, performing it in the digital domain introduces new challenges. The details of these challenges and how to deal with them are also explained. This thesis presents the design of a digital stereo FM modulator including necessary signal processing, such as filtering, waveform generation, stereo multiplexing etc. The solution is comprised of code written in Very high speed integrated circuit Hardware Description Language (VHDL) and a selection of free Intellectual Property (IP)-blocks and is intended for implementation on a Xilinx FPGA. The focus of the thesis lies on area efficiency and a number of suggestions are given to maximize the number of channels that can be modulated using a single FPGA chip. An estimation of how many channels that can be modulated usingthe provided FPGA, Xilinx XC6SXL100T, is also presented.
