Digital signal processing capabilities of DE2-115

My advice to you, Propaste, is to follow the advice of Dave Hawkins (the post above) closely, as he is an FPGA/DSP expert and has written some excellent tutorials on the subject. As an undergraduate you shouldn't pick something overly complex, you're not trying to break new ground. You need to demonstrate to your instructor that you have a solid grasp of the fundamentals and can apply them to a practical problem. Good Luck.
