Digital Filters. Your Assistant for Modern Filter Analyses
Discover the latest design techniques for easiest operation. The FlexPro 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.
Benefit from the enhanced IIR filters which include internal feedback (recursive filters) and provide a high degree of steepness with a short filter length. Use the IIR filters to design low pass, high pass, bandpass and bandstop filters.
FlexPro also offers you two procedures for calculating phase-linear filters with a minimum filter length. These FIR filters avoid feedback and are therefore always stable.
Performance Features
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
CFC stands for Channel Frequency Class, a 4-pole phaseless Butterworth filter used primarily for crash tests and implemented in accordance with ISO 6487.
