The FlexPro® Digital Filter Analysis Wizard merges steps for filter design, filtering and presentation into a simple sequential process. Using real-time 2D and 3D graphics, FlexPro® offers you immediate visual feedback whenever any change is made to the filter specification.
Enhanced IIR filters
IIR filters include internal feedback (recursive filters) and provide a high degree of steepness with a short filter length, making it possible to design low pass, high pass, bandpass and bandstop filters.
FIR filter design
FIR filters avoid feedback and are therefore always stable. FlexPro® offers you two procedures for calculating phase-linear filters with a minimum filter length.
- FIR filter design using the window method
Use the Kaiser or Chebyshev windows to specify the filter’s length, attenuation, and transition width more precisely. You only have to provide two parameters. The third parameter is calculated automatically.
- FIR filter design using the equiripple method
In addition to the standard low pass, high pass, bandpass and bandstop filters, you can use this method to design any type of multiband filter.
- Smoothing filter
Use this filter to smooth signals whose peaks are to be preserved as accurately as possible.
- CFC filter
Channel Frequency Class (CFC) filter is a 4-pole phase-less Butterworth filter used primarily for crash tests and implemented in accordance with ISO 6487.
