arim.signal.Hanning

class arim.signal.Hanning(nsamples, centre_freq, half_bandwidth, time)

Bases: Filter

Hanning Filter - Apply the Hann function.

Return the analytical signal

Parameters:

• nsamples (int) – len(time)

• centre_freq (float) – In Hz

• half_bandwidth (float) – In Hz

• time (arim.Time) – Time object. This filter can be used only on data sampled consistently with the attribute

• time.

• force_zero (bool) – If True (default), the spectrum amplitudes below -db_down will be replaced by exactly zero.

• db_down (float)
