- FilterAnalyzer 2.32 requires color QuickDraw, at least 16 colors or grays,
- and an FPU or 68040. There is another version that doesn't require an FPU,
- and can be found on this FTP site under a similar name.
-
- This program is a simple, but elegant, active filter response analysis tool.
- It has the ability to simulate the frequency response (magnitude and phase)
- of single- or multi-stage filters built with common first- and second-order
- active filter stages. It can calculate the Q and natural frequency of standard
- second-order filter stages. There are a number of graphing options including
- the ability to change the range and number of points per decade along the
- frequency axis. It can also plot the response magnitude in standard voltage
- ratio or decibel formats, and has a cursor feature that will display the
- magnitude and phase at the frequency where you click the mouse. It will
- print the plots that you generate with a number of useful print options, and
- save filter configurations as FilterAnalyzer data files.
-
- FilterAnalyzer 2.32 is distributed as shareware in the hopes that users will
- be honest and pay the US$15 registration fee which will entitle the user to
- free future updates and information on new simulation and design software
- releases by the author. Please read the registration stuff.
-
- I cannot be held responsible for any bad things that happen to you or your
- company as a result of using this software. It is being released as what I
- like to refer to as use-at-your-own-risk-ware. I feel that the program will
- produce accurate results, but was written mostly to provide quick plots for
- visualization purposes only. I will be releasing my second program,
- FilterDesigner in a few months. This program will be quite a bit more
- advanced (although this one isn't too bad), and provide an attractive interface
- along with powerful design capabilities.
-
- I would appreciate bug reports, and shareware fees! :-)
