A library to generate partial and/or complete log power spectrums of an input signal in C. The library makes a couple of assumptions listed below which have been hard-coded into the source code.
- The windowing function is the hann function.
- The window size is 128.
sudo apt-get install -y build-essential binutils g++ gcc scons
$] sudo apt-get install -y libgtest-dev
$] cd /usr/src/gtest
$] sudo cmake CMakeLists.txt
$] sudo make
$] sudo cp *.a /usr/lib
The libspectrum library uses the Intel Performance Primitives Library. When installing this library make sure the install path is changed to /var/lib/intel. If the library is installed to a different location then the IPP_INCLUDEPATH and IPP_LIBPATH variables have to be updated in the SConstruct file located in the the project's root folder.
After the installation is complete create a new file /etc/ld.so.conf.d/intel_ipp.conf and paste the following into it:
/var/lib/intel/compilers_and_libraries_2017.0.098/linux/ipp/lib/intel64
Keep in mind if the library was installed to a different path then the path should be updated in the /etc/ld.so.conf.d/intel_ipp.conf file as well.
Finally, inform the dynamic loader of our new libraries by running the following command:
$] sudo ldconfig
$] git clone https://github.com/thomasquintana/libspectrum.git
$] cd libspectrum
$] scons
Once, libspectrum is compiled run the unit tests.
$] tests/test_runner
$] doxygen Doxyfile
