Owning Class: filter design
Requires: MathScript RT Module
Syntax
b = freq_space(a)
b = freq_space(a, 'whole')
[b, c] = freq_space(a)
[b, c] = freq_space(a, 'meshgrid2d')
Legacy Name: freqspace
Description
Generates frequency spaces for 1D and 2D applications. If you request one output and do not specify 'whole', freq_space assumes a equally spaced points around the upper half of the unit circle. If you request two outputs, freq_space returns the 2D frequency range vectors.
Inputs
| Name | Description |
|---|---|
| a | Specifies the number of equally spaced points around the unit circle. If you request two outputs, a can be a 1-by-2 vector. |
| 'whole' | Directs LabVIEW to evaluate the frequency response at a points equally spaced around the unit circle. |
| 'meshgrid2d' | If you specify 'meshgrid2d', [b, c] = freq_space(..., 'meshgrid2d') is equivalent to [b, c] = freq_space(...); [b, c] =meshgrid2d(b, c). |
Outputs
| Name | Description |
|---|---|
| b, c | Return the equally spaced frequency responses. |
Details
The following table lists the support characteristics of this function.

Examples
b = freq_space(10)
b = freq_space(5, 'whole')
[b, c] = freq_space(10, 'meshgrid2d')
