# scipy.signal.daub

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:
    p int

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

  Returns:
    daub ndarray

      Return
