This calculator is designed for electrical engineers seeking to design Butterworth and Chebyshev filters. It provides quick and accurate calculations to help in designing effective filters for various applications.
All calculations are based on the formulas provided by IEEE standards for filter design.
The transfer function for Butterworth filters is defined as:
\[ H(s) = \frac{1}{\sqrt{1 + \epsilon^2 (\frac{\omega}{\omega_c})^{2n}}} \]
A Butterworth filter is designed to have a frequency response as flat as possible in the passband.
The filter order depends on the desired steepness of the transition band and the specific application requirements.
