scipy.signal.daub(p)

The coefficients for the FIR low-pass filter producing Daubechies wavelets.

Deprecated since version 1.12.0: scipy.signal.daub is deprecated in SciPy 1.12 and will be removed in SciPy 1.15. We recommend using PyWavelets instead.

p>=1 gives the order of the zero at f=1/2. There are 2p filter coefficients.

Parameters:

pint

Order of the zero at f=1/2, can have values from 1 to 34.

Returns:

daubndarray
