* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-033-6/+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-analog: clean up examplesClayton Smith2020-02-033-1954/+1518
| | | | | | | | | | | | | | | I've converted the fm_tx and fm_rx examples to YML, and also made a few corrections so that the flow graphs work properly: * increased the output sample rate from 200k to 400k to fix distortion * added missing deemphasis to fm_rx * removed superfluous division by 8.0 from quadrature demod in fm_rx * increased output volume in fm_rx from 0.2 to 1.0 After these changes, a dial tone is heard when running fm_tx followed by fm_rx. I also lined up the blocks in the noise_power flow graph.

* 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.
* analog: Convert flowgraphs to YAML formatJohannes Demel2019-01-121-1675/+481
| | | | | This is part of an ongoing effort to convert all flowgraphs in GR to the new YAML format.
* Replace scipy/pylab where numpy/pyplot is sufficientMarcus Müller2018-11-021-20/+14
| | | | | | | | | 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.

* cmake: nuke cpack from existenceJohnathan Corgan2016-08-032-3/+0
| | | | | | CPack is not used, unmaintaned, and broken. This does not eliminate any MSVC build functionality.
* gr-analog: Add safety and default for FM preemphasis filterAndy Walls2016-03-301-2/+2
| | | | | | | | | | | | | 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/+2
| | | | | | | Add working filters designs for the FM preemphasis Tx filter. Rework the FM deemphasis Rx filter as it was easier to rederive the transfer function, than to determine if the one in use was correct.
