Member of the filter implementation class.

Syntax

[bz, az] = impinvar(bs, as)

[bz, az] = impinvar(bs, as, fs)

[bz, az] = impinvar(bs, as, fs, tol)

Description

Applies a digital filter whose impulse response equals the impulse response of an analog filter.

Examples

Inputs

Name	Description
bs	Specifies the numerator coefficients of the analog filter. bs is a vector.
as	Specifies the denominator coefficients of the analog filter. as is a vector.
fs	Specifies the sampling rate. The default is 1.
tol	Specifies the tolerance used to classify the poles. The default is 0.

Outputs

Name	Description
bz	Returns the numerator coefficients of the digital filter. bz is a vector.
az	Returns the denominator coefficients of the digital filter. az is a vector.

Examples

[b, a] = impinvar([1 2 3], [1 5 9 7 2])
