»View Product Info

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.

Examples

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
