Filter Wiz PRO Screenshot

Active filter design software 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.

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