Filter Designer is an interactive Macintosh OS 10.7 (Lion) or greater application which allows the designer to enter electronic filter specifications and subsequently obtain the element values. Low-pass, high-pass, band-pass and band-stop lumped element filters in Butterworth, Chebyshev, and Bessel configurations are supported. S-Parameter analysis of the filter is performed, and a schematic generated.
