Conclusion

If we take a look at where we have been in this series: we have considered how to generate signals that can be used to manipulate the outside world, how to measure how the outside world is responding to our signals, how to create a closed loop controller to make the external system behave in the particular manner that we desire. In recent columns we have looked at how to handle signals that are time varying and how to modify those signals with filters. This time we enhanced our filtering ability to be able to adaptively modify a signal.

Next time, I am going to shift gears a bit and spend some time considering the software development process itself.
