Owning Class: filter design
Requires: MathScript RT Module
Syntax
b = fir_gauss(k, l)
b = fir_gauss(k, 'minorder', v)
[b, l] = fir_gauss(k, 'minorder', v)
Legacy Name: firgauss
Description
Uses cascading uniform coefficient filters of length l to design a digital FIR Gaussian filter.
Inputs
| Name | Description |
|---|---|
| k | Specifies the number of uniform coefficient filters. k is a positive integer. |
| l | Specifies the length of the uniform coefficient filters. l is a positive integer. |
| 'minorder' | LabVIEW uses the minimum length of the uniform coefficient filters. |
| v | Specifies the variance of the Gaussian filter. v is a positive number. |
Outputs
| Name | Description |
|---|---|
| b | Returns the coefficients of the Gaussian filter. |
| l | Returns the length of the uniform coefficient filters. |
Details
