FIR and IIR Filter Design

The Filter Design Toolbox enables you to design advanced FIR and IIR filters, import designed filters to Simulink, quantize floating-point filters, and analyze quantization effects. You can design filters from the MATLAB command line, in Simulink with the filter design block library, or from a graphical user interface such as FilterBuilder in the toolbox or Filter Design and Analysis Tool (FDATool).

Design Methods

The toolbox supports a number of design methods, including:

Advanced equiripple FIR filters, including minimum-order, constrained-ripple, minimum-phase designs

Nyquist and halfband FIR and IIR filters, providing linear phase, minimum-phase, and quasi-linear phase (IIR) designs, as well as equiripple, sloped-stopband, and window methods

Optimized multistage designs, enabling you to optimize the number of cascaded stages to achieve the lowest computational complexity

Fractional-delay filters, including implementation using Farrow filter structures well-suited for tunable filtering applications

Allpass IIR filters with arbitrary group delay, enabling you to compensate for the group delays of other IIR filters to obtain an approximate linear phase passband response

Lattice wave digital IIR filters, for robust fixed-point implementation

Arbitrary magnitude and phase FIR and IIR, enabling design of any user-specified filter
