Whether new to active filters, or experienced in their design, Filter wiz PRO is the right application for you.

Unlike cookbooks, textbooks and simple freeware calculators, Filter Wiz PRO offers in-depth design and highly customizable solutions.

Features:

* Quality Factor (Q) versus Filter Order (Q-N) plot
- now you can visually compare all available approximations to find not only which are All-Pole, and which have (more complex) notch stages, but also quickly find those Approximations with both low Filter Order and low Maximum Q (thus providing greater filter stability).

* Antialiasing Filter design
- design an antialiasing lowpass filter for A/D conversion

* Op Amp selector and Slew Rate Calculator tools
- find suitable op amp families by sorting on GBW, slew rate or quiescent supply current

* upgraded interface
- allows instant access to all completed phases of the filter design, and presents information and choices with clarity and ease of use
- Version 5 works best with 1024x768 screen resolution or higher

* built-in simulator
- provides eSketch-like simulation of the filter design, including effects of op amp Gain BandWidth. The user can preview the gain response when selecting circuits for each stage. And now Filter Wiz PRO can export eSketch .ES1 files, providing two ways of transferring data from Filter Wiz PRO to eSketch PRO

* up to 21 Approximations available
- choose from 10 "standard" Approximations, plus 5 linear phase Approximations, and 6 Low-Q Approximations that are extremely useful for augmenting filter stability

* many circuit topologies to implement filter
- includes new topologies (circuits), and many variations of existing topologies, including voltage divider inputs to better meet optimal stage gain requirements.

* cascaded stages
- filters of order 3 to 20 are constructed of simpler first and second order stages cascaded together. Filter Wiz PRO lets you know what the circuit response should be for each stage, thus making tuning or troubleshooting easier.

* more selection aids
- in addition to stage gain simulation, view indicators of stage Noise (resistor noise), GBW requirement, and Gain Spread. Also view design windows showing Input Impedance (vs frequency), Passive Sensitivity, Active Sensitivity, Dynamic Range, and Tuning instructions

* Monte Carlo analysis
- simulate gain spread due to inexact component values, with a choice of 3 probability distributions - Uniform, Gaussian and Worst Case

* Temperature Effect analysis
- determine response change due to environmental temperature rise and component temperature coefficients

* "Strategy" help windows
- view help topics appropriate to each design phase, accessible through "Strategy" buttons. All help topics are also available through a standard help file
