# scipy.signal.daub¶

scipy.signal.daub(p)[source]

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

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
