Next: References Up: number6 Previous: Sampling a time dependent


This installment further extends our ability to handle data coming in from the outside world. We have just scratched the surface of the issues involved in dealing with frequency dependent data. For more information about handling time dependent signals see the references, the book by Oppenheim and Schafer is especially thorough, but its not for the mathematically timid. Next time we will close the loop between our input and output handling and look at how we can modify our outputs on the basis of the given inputs in order to provide stable control of a system.
