| * | examples: wavetable: Modify wave tables to ease power calculations | Martin Braun | 2020-04-15 | 1 | -19/+24 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing implementation would create a real signal for any type of signal (CONST, RAMP, SQUARE, and SINE), and then create the complex signal by simply delaying the Q value by a 90 degree phase. This had surprising results for all waveforms: - CONST waveforms would have a baseband value of ampl + j ampl, thus increasing the output power by 3 dB vs. what one would expect when setting an amplitude. It is now ampl + j * 0, and the power is ampl**2. This now makes the power consistent with SINE, which it was not, even though a const signal is a sine signal with a frequency of zero. - SQUARE waveforms would phase-delay the Q part, thus resulting in three power output levels (when both phases are zero, when both phases are ampl, and when one of them is zero and other is ampl). However, the square signal is useful for watching it in the scope, and there, it helps if the power is predictably either high or low within the selected frequency. The Q value is now always zero. - RAMP waveforms had the same issue and were also resolved by setting Q to zero. - SINE signals were fine, although the implementation used sin + j cos to calculate a complex sine, not cos + j sin according to Euler's formula. To make this wavetable more useful with absolute power settings, the changes mentioned above were implemented. The dBFs power of CONST and SINE can now be calculated by using ampl**2, SQUARE by using (ampl**2)/2, and RAMP by solving the integral over a ramp from -1 to 1. | ||||
| * | uhd: Apply clang-format against all .cpp and .hpp files in host/ | Martin Braun | 2020-03-03 | 1 | -1/+2 |

| * | uhd: mpm: apply clang-format to all files | Brent Stapleton | 2019-01-16 | 1 | -29/+25 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applying formatting changes to all .cpp and .hpp files in the following directories: ``` find host/examples/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/tests/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/neon/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/dboard/magnesium/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/device3/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/mpmd/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/lib/usrp/x300/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find host/utils/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file find mpm/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Also formatted host/include/, except Cpp03 was used as a the language standard instead of Cpp11. ``` sed -i 's/ Cpp11/ Cpp03/g' .clang-format find host/include/ -iname *.hpp -o -iname *.cpp | \ xargs clang-format -i -style=file ``` Formatting style was designated by the .clang-format file. | ||||
