FilterLab® is an innovative software tool that simplifies active filter design. Available at no cost, the FilterLab® active filter software design tool provides full schematic diagrams of the filter circuit with component values and displays the frequency response.
Allows the design of low-pass filters up to an 8th order filter with Chebyshev, Bessel or Butterworth responses from frequencies of 0.1 Hz to 10 MHz
Selection of flat passband or sharp transition from passband to stopband
Options, such as minimum ripple factor, sharp transition and linear phase delay, are available
Changes in capacitor values can be implemented
Generates a spice model of the designed filter allowing time domain analysis in spice simulations
