Owning Class: filter implementation

Requires: MathScript RT Module

Syntax

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

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

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

Legacy Name: impinvar

Description

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