CST Microwave Studio Advanced Topics Manual

Hi, Can anyone provide me documentation in detail on what AR filter can do in MWS (obviously it extrpolates the FDTD signals). I want to know the meaning of various terms involved and how to use them to obtain accurate results. Thanks.

See section 4.7 of the CST MWS Advanced Topics Manual (attached below) for a discussion of the use of Auto-Regressive (AR) Filtering. Sorry to upload the whole manual, but I could not separate the section of interest...

This manual is primarily designed for advanced users of CST MICROWAVE STUDIO?
(CST MWS) who are already familiar with the basic concepts of using the software.
Before you actually start reading this book, we strongly recommend that you carefully
work through the Getting Started manual and the Tutorials. Since a lot of changes have
been introduced in version 5 of CST MWS, it may be helpful even for experienced users
of earlier versions to have a look at these documents again.
This collection of Advanced Topics offers some additional information on subjects which
are usually of a more involved nature. The following list gives a short summary of this
manual?s contents:
? Chapter 2 provides a brief overview of the most important newly introduced
features of CST MWS 5.
? Chapter 3 focuses on the basic principles of importing CAD data in two and
three dimensions. Some hints are given on how to improve the robustness and
reliability of exchanging CAD data files.
? Chapter 4 is dedicated to the FI method which is the underlying mathematical
simulation technique. After a general introduction into the method?s
fundamentals, the PBA technique (Perfect Boundary Approximation) is also
introduced. Further sections in this chapter then explain possible sources of
errors or inaccuracies and discuss meshing strategies. Finally some hints on
how to tune the performance of a simulation are given.
? Chapter 5 provides an introduction to the key concepts of the VBA-based
macro programming language used in CST MWS. You will obtain some
information on the most important VBA elements by means of a couple of
examples. A basic understanding of these language elements will be very
helpful for you in order to write your own macros and user defined functions.
? Chapter 6 gives an overview of the preinstalled macros, which contain many
time saving solutions to automate common tasks. For each of these macros an
introduction is provided which should enable you to make use of that particular
macro. You may even get some ideas of how to use automation for your daily
work.
? Chapter 7 explains the available result templates and how they can be utilized
to automate the post processing.
? Chapter 8 describes several options to install CST MWS on a local area network
and how to setup the distributed network computing feature.
Please note that this book is not intended to be a complete reference guide. For
successfully mastering these more advanced topics we strongly recommend that
you visit a specialized training class. Please contact your local support center for
more information.

OK, now I've managed to excerpt the 7 pages from the manual on AR Filtering, but alas, they're all on a single PNG image...but still very legible.
