Easy to use 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 wide variety of circuit choices. Up to 11 alternate Approximation types including stable low-Q types.
Built-in simulator provides accurate picture of filter performance. Filter circuit can be exported to eSketch simulation software for further analysis. Resistor values are masked in demo version.
