* qtgui: freq_sink: Allow normalization of window functionsMartin Braun2020-08-1711-7/+67
| | | | | | | | | | | | | | | | | | | | When switching between window functions in a live FFT GUI session, the difference in power of the window functions is notable. This allows asserting the 'normalize' argument of fft::window::build() by setting a bit in the window type during construction,, or by calling a new API call: set_fft_window_normalized(). Note: The choice to use an unused bit to set the normalization comes from an attempt to keep the API backward compatible. Adding a new argument to the make call would require reordering the make arguments. This feature allows changing window types without signal power varying due to window power differences. Note that this does not affect scalloping loss, or processing loss from the window. For example, the peak value of a sine tone will still vary for different windows, because different windows distribute the power differently, and most window functions move power to the sidelobes.

* qtgui: Replace firdes::window with fft::windowMartin Braun2020-08-1417-101/+98
| | | | | | | | | | | | The former has been declared deprecated, hence the shift. Note that this is 100% search and replace. The three things changed are: - gr::filter::firdes --> gr::fft::window - #include <gnuradio/filter/firdes.h> --> #include <gnuradio/fft/window.h> - filter::firdes::window(...) --> fft::window::build(...) - The default beta = 6.76 parameter is removed, since it's the default value from the window generator
* python: Remove unnecessary 'from __future__ import'Oleksandr Kravchuk2020-08-0316-31/+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.

| * qtgui: fix typo and enum in qtgui_sink.ymlJosh Morman2020-06-041-2/+2
| | | | | | | | | | | | | | | | Because of pybind11 bindings, there is an extra parameter needed in the declaration of the qtgui blocks that should default to None Also, the ints being passed to enums cause an issue, but changing the to enum in the yml file fixes that

* Remove VOLK as a submoduleMartin Braun2020-04-112-2/+1
| | | | | | | | | | | | | | This removes the volk/ submodule pointer and updates the CMake to detect VOLK like any other dependency. The VOLK_MIN_VERSION CMake variable is added (and set to 2.1.0). The GR_VOLK_LIB variable is replaced with Volk::volk everywhere. The VOLK_INSTALL_LIBRARY_DIR and VOLK_INSTALL_INCLUDE_DIR variables weren't used and were removed. CMake will now fail if VOLK cannot be detected. Therefore, ENABLE_VOLK was also removed as a variable; all in-tree components may assume the existence of VOLK.

* Replace many `const` variables with `constexpr`Thomas Habets2020-01-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constexpr is like const but (for variables) guarantees evaluation at compile time (as opposed to runtime). Likely this change will do nothing on its own (though it could, since it gives the compiler more information). But it still has benefits. It allows programmer to know that initialization is not expensive (it was done at compile time), and reduces risk of a refactoring regressing the compiletimeness. Runtime initialization can be nonobvious in larger codebases. E.g.: struct S { static int foo(); }; const int bar = S::foo(); // Called and initialized at *runtime*. int S::foo() { return 10; } With constexpr: struct S { static constexpr int foo(); }; constexpr int bar = S::foo(); // Error: used before definition. constexpr int S::foo() { return 10; } Initializing at runtime is not just startup costs, but also can save memory since it'll end up in a R/O section of a binary and therefore doesn't need to be swapped out, but can be shared (in the mmap() sense of the word).
