Conclusion and Future Work

As for the future, we believe that much of what has been done here can now be accomplished through careful software design and the power of high-speed computing. When this project started several years ago, the dominant software approach was not possible or practical: today, it should be possible. In theory, with careful sampling techniques, direct digital synthesis strategies, creative computer code, and high speed digital to analog conversion techniques, much of the electrical hardware shown here could be eliminated or greatly simplified.
