Filter Wiz PRO 4.3

Filter Wiz PRO 4.3 is an active filter design software designed for lowpass, highpass, bandpass and bandstop electronic filters using resistors, capacitors and op amps. Provides Butterworth, Chebyshev, Elliptic and Bessel Approximations to order 20, with a variety of circuit choices.

This new version represents a major advance in the rapid design of stable and effective active filters.

Filter Wiz PRO can be freely downloaded for evaluation, without time restriction. Resistor values and some additional output data are masked. This masking is removed once a license is purchased and the registration information is entered. 

Major Features:

1. Completely new interface - allows instant access to all completed phases of the filter design, and presents information and choices with clarity and ease of use

2. Built-in simulator - provides eSketch-like simulation of the filter design, including effects of op amp Gain BandWidth.
   

3. 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

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

5. More selection aids - in addition to stage gain simulation, view indicators of stage Noise (resistor noise), GBW requirement, and Gain Spread.
   

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

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

8. "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

Requirements: no special requirements.
