Daubechies Filter Creation

Description

Computes the Daubechies' scaling and wavelet filters (normalized to sqrt(2)).

Usage

daubcqf(N, type = PHASE.MINIMUM)

Arguments

N Length of filter (must be even)
type Distinguishes the minimum phase, maximum phase and mid-phase solutions. Valid values are:
PHASE.MINIMUM
PHASE.MID
PHASE.MAXIMUM

Value

Returns a list with components:

h.0 Minimal phase Daubechies' scaling filter
h.1 Minimal phase Daubechies' wavelet filter
