【 摘 要 】

Problem statement: Arbitrary signal generators play an important role in manyapplications. Several different techniques utilizing both analog and digital approaches are being usedfor the generation of periodic signals. However, all of them suffer from many drawbacks. In this study,we present modeling, simulation and prototyping of a novel periodic arbitrary signal generation systemusing FPGAs. The proposed system utilizes orthogonal functions to generate a variety of periodicarbitrary signals. Approach: A new approach for designing arbitrary signals utilizing Walsh andRademacher functions had been used. The design had been done using state-of-the-art high leveldesign techniques and has been targeted to the latest available FPGA chips from Xilinx and Altera.Results: The simulation results demonstrated both the digital and analog versions were presented. Itwas found that all the signals generated showed precisely zero error and the signal generated wasexactly the same as the desired one. Conclusion: Excellent accuracy with zero error is achieved. Thedesigned and implemented Arbitrary signal Generation System is stand-alone and doesn
