Filter Designer 1.4.1
A reliable software application which allows users to quickly design Chebyshev, Butterworth or Bessel lumped element filters
The interaction with the application is done through a plain-looking user interface where you can enter the cutoff frequency, attenuation frequency, attenuation, number of prototypes. Afterwards, click the button to calculate the low-pass prototype and view the resulting values, as well as the generated Butterworth Low-Pass Filter Prototype graph.
The application supports low-pass, high-pass, band-pass and band-stop lumped element filters. In the calculation process and before generating the Butterworth schematic, Filter Designer performs an S-Parameter analysis of the filter. In addition to this, users can also view the filter values and schematic from a separate window.
Besides being able to perform complex calculations rapidly, Filter Designer offers support for printing the prototype and the element table, response and schematic filters. Moreover, you can choose a different characteristic impedance and change the frequency unit, filter type, configuration and implementation.
To conclude, Filter Designer is quite a powerful piece of software for working with lumped element filters. It can calculate low-pass prototypes in an instant and display an intuitive Butterworth filter graph, which can be easily printed and used in your paper. On top of that, it is very easy-to-use and the memory and CPU footprint is low.
