Frequency and Magnitude Specifications Region:
Arbitrary Group Delay

Select the units for frequency specifications from the Frequency units list:

• Hz
• kHz
• MHz
• Normalized (0 to 1), where 1 corresponds to the Nyquist frequency

For all units except Normalized, specify the sampling frequency, Fs.

Specify the following parameters in the text boxes:

• Freq. vector - A vector defining the frequency points at which the response group delay is specified, in ascending order. Must have the same length as Grp. Delay vector.
• Freq. edges - A vector defining the band-edge frequencies on the boundary between "care" and "don't care" regions, in ascending order. The Freq. edges vector contains a subset of the points in the Freq. vector vector.
• Grp. Delay vector - A vector defining the response group delay in samples at the specified frequencies. Must have the same length as Freq. vector.
• Weight vector - A vector defining the relative weight that should be given to each frequency-group delay pair. Must have the same length as Freq. vector.
• Max pole radius - A scalar in the range [0 1] specifying the maximum allowable magnitude for any pole.

The Arbitrary Group Delay filter type is available only when the Filter Design Toolbox is installed. See iirgrpdelay in the Filter Design Toolbox documentation for more information.
