Windipoles

Windipoles is a free passive filter simulator.
Windipoles enables design, analysis, optimizations and plots, all graphically.
While component values are changed, graphic windows are updated instantly.
Graphics may show, overlapped, more than one network for comparing purposes.
Also, synthesizes Butterworth, Bessel, Chebyshev (types I & II), and Cauer (elliptic) filters.
Current version is v4.8.11

This is my old Polynomials and Scientific calculator. It can perform operations with polynomials (+, -, *, /), find the roots, logarithmic, trigonometric and exponential functions, or define custom functions, in the field of real or complex numbers. It also incorporates constants such as 'pi' and 'e'. Also you can enter binary, octal or hexadecimal numbers by prepending &b, &o and &h. Other features are calculus of derivatives, integrals, Lagrange interpolation; matrix operations and resolution of systems of equations and differential equations. In some cases, you may consult the examples or the intermediate steps.
