Automatically design lowpass, highpass, bandpass, or bandstop filters with Butterworth, Cheby-I, Cheby-II, or Elliptical characteristics. It provides real-time design and simulation, phase analysis, and code generation. Test signals can be applied and results displayed in time or frequency domains. Filter coefficients can be exported for further use.
