Signal Processing Toolbox

Filter Order Region

Select a radio button to compute one of the following:

• Filter of the order you specify (Specify order)
• Minimum order filter (Minimum order). The computed filter has the minimum order estimated to meet the specifications.

For certain menu choices in the Design Method region, only one of the above order options is available.

For Arbitrary Magnitude IIR filters, Lowpass IIR Maximally flat filters, IIR Least Pth-norm, or IIR Constrained Least Pth-norm filters, independently specify the following:

• Order of the transfer function numerator (Numerator order)
• Order of the transfer function denominator (Denominator order)
