PaddedTaskBase

class baseband_tasks.base.PaddedTaskBase(ih, pad_start=0, pad_end=0, *, samples_per_frame=None, **kwargs)

Bases: baseband_tasks.base.TaskBase

Base for tasks which need more points than they produce.

Like TaskBase, subclasses should define:

task(self, data) : return processed data from one frame.

Where data will contain extra padding. The task method has to ensure the right selection is returned, and can use the _pad_start and _pad_end attributes for this purpose.

Parameters

ihstream handle

Handle of a stream reader or another task.

pad_start, pad_endint

Padding to apply at the start and end. Default: 0.

samples_per_frameint, optional

Number of output samples which should be produced in each frame. The number of input samples will be larger by the padding. If not given, the minimum power of 2 needed to get at least 75% efficiency.

**kwargs

Possible further arguments; see BaseTaskBase.
