The Filter Design Toolbox builds upon the Signal Processing Toolbox by adding advanced filter design algorithms, fixed-point filter analysis
and simulation, multirate filters, and adaptive filters. Some of the
key features for the Filter Design Toolbox are:
- Design and analysis of filters from the FDATool GUI or from the command line
- Advanced FIR filter design methods: generalized Remez, halfband, Nyquist, interpolated FIR, CIC compensators, inverse-sinc, minimum-phase, constrained-ripple, sloped stopband, least Pth-norm, and perfect reconstruction 2 channel filter banks.
- Advanced IIR filter design methods: arbitrary group-delay equalization, comb filters, peaking/notching filters, arbitrary magnitude, constrained radius.
- IIR frequency transformations to convert lowpass filters into bandpass, multiband and complex filters among others.
- A suite of multirate filtering efficient polyphase structures for interpolation, fractional interpolation, decimation, fractional decimation, and sampling-rate conversion.
- Support for CIC-interpolation and CIC-decimation.
- An extensive suite of adaptive filtering algorithms including steepest-descent type, least-squares type, frequency-domain and block adaptive filters.
- Fixed-point implementations of various filter structures including, direct-form FIR and its transposed version, symmetric/antisymmetric FIR, direct form I and II second-order sections, and polyphase interpolators/decimators/sample-rate converters.
- Scaling of second-order section IIR filters for fixed-point implementation.
- Estimation of the power spectral density estimation for round-off noise in fixed-point digital filters.
- Limit cycle analysis for fixed-point IIR filters
