Filter Wiz LE is a lite version of Filter Wiz PRO active filter design software.

Features:
approximately 1/2 of the topologies (circuits) offered in the PRO version compare additional differences between the LE and PRO versions design up to order 20 lowpass, highpass, bandpass or bandstop filters filters comprised of linear sequence of order 1 or order 2 subcircuits (stages) little or no prior expertise required
incorporates intuitive sequence of design steps that avoid the confusion of menu-based systems allows for rapid viewing, comparison and selection of Approximations and circuit topologies
provides control over pole-zero pairing, stage sequencing, stage gains and filter sensitivities to changes in component values
Filter Wiz design files can be imported directly into eSketch, allowing for Monte Carlo Analysis, Parameter Sweep Analysis, merging with other design files, and much more.
