* qtgui: Replace pyqwidget() with qwidget()David Winter2021-09-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Previously, two versions of the `qtwidget` functions existed, `qwidget()` and `pyqwidget()`, with the only difference being that `qwidget()` returned a pointer to the `QWidget` object managed by the corresponding block, while `pyqwidget()` returned that same pointer, but as an integer (Or `PyLong` in this case). While `qwidget()` is used by C++ code accessing the widgets, `pyqwidget()` is only used for the python interface. This makes these two methods redundant, thus this commit entirely removes `pyqwidget()`, and modifies the `qwidget()` python wrapper to behave like `pyqwidget()`. Note that we can be fairly confident that this change will not effect potential users of `qwidget()`, because any invocation on the objects previously returned by `qwidget()` would cause a segmentation fault. This commit also fixes a memory leak: Internally, the `pyqwidget()` functions were returning a PyLong `PyObject *`, which was then upwrapped in a pybind trampoline without decrementing the reference count of that python object.

* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-0316-43/+0
| | | | | | | | | | | | | | | | All of the removed `from __future__ import` were needed in older versions of Python (mostly 2.5.x and below) but later became mandatory in most versions of Python 3 hence are not necessary anymore. More specifically, according to __future__.py[1]: - unicode_literals is part of Python since versions 2.6.0 and 3.0.0; - print_function is part of Python since versions 2.6.0 and 3.0.0; - absolute_import is part of Python since versions 2.5.0 and 3.0.0; - division is part of Python since versions 2.2.0 and 3.0.0; Get rid of those unnecessary imports to slightly clean up the codebase.

* gr-filter: Add ichar/ishort decimatorghostop142020-02-201-0/+299
| | | | | | | | | Current resamplers do not support ichar and ishort as an input type. When processing streaming ichar data from external sources (such as the ATA), decimation in native ichar would be faster than converting to another data type then decimating. This block provides the ability to decimate the ichar stream directly. Support was also added to support ishort data in the same manner.

* gitignore: ignore autogen files in example foldersJohannes Demel2019-03-241-0/+1
| | | | | This commit adds `.gitignore` files to some example folders. This helps to keep auto generated files out of commits.
* filter: Convert GRC examples to YAML formatJohannes Demel2019-01-153-4084/+1166
| | | | | | | | This commit converts the examples in `gr-filter` to the new YAML format. This conversion is tracked in #2285. Also, in order to make all examples work, the YAML block definition for the *band_pass_filter_taps* is updated.
* Replace scipy/pylab where numpy/pyplot is sufficientMarcus Müller2018-11-0211-174/+115
| | | | | | | | | This should reduce the number of times users are prompted to install pylab || scipy when they'd actually get away with functionality fully contained in numpy and matplotlib. This only solves the obvious cases. There's some usage of `pylab.mlab` that would need more than 20s of consideration.

* | gr-analog: Add safety and default for FM preemphasis filterAndy Walls2016-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The FM preemphasis filter design now precludes the user from inducing a pole on the unit circle at z = -1.0 and z = 1.0. A pole at either of these locations makes the filter unstable and useless: feeding back "+/-inf" into an IIR filter has no good recovery. Also provide a reasonable, maximally safe default of 0.925*fs/2.0 for the high frequency corner, fh. This keeps the slope of the preemphasis filter looking reasonable sane in the whole band; at least for tau=75e-6 and fs=48000.
* | gr-analog: Fix FM preemphasis filter and rework deemphasis filterAndy Walls2016-03-291-1/+1
