Taper Edge Effects

taper is often used to manage “edge effects” associated with several other types of processing such as filtering. For example:

Bandpass filtering without tapering

import dascore as dc

patch = (
    dc.get_example_patch('example_event_1')
    .pass_filter(time=(None, 300))
)

patch.viz.waterfall(show=True);

Bandpass filtering with tapering

import dascore as dc

patch = (
    dc.get_example_patch('example_event_1')
    .taper(time=0.05)
    .pass_filter(time=(None, 300))
)

patch.viz.waterfall(show=True);
