- cosine_sac_taper(freqs, flimit)¶
Generate a cosine flank frequency domain taper similar to the one SAC applies before instrument response deconvolution. This acts as a bandpass filter when applied to the data in frequency space.
- freqs (numpy.ndarray) frequency vector to use
- flimit (tuple of 4 floats) sequence containing the 4 frequency limits
The flimit parameter is a tuple of four frequency values (f1, f2, f3, f4), the following plots illustrates the concept:
