daubcqf {rwt} | R Documentation |
Computes the Daubechies' scaling and wavelet filters (normalized to sqrt(2)).
daubcqf(N, type = PHASE.MINIMUM)
N |
Length of filter (must be even) | |||
type |
Distinguishes the minimum phase, maximum phase and mid-phase
solutions. Valid values are:
|
Returns a list with components:
h.0 |
Minimal phase Daubechies' scaling filter |
h.1 |
Minimal phase Daubechies' wavelet filter |
