Coding examples
This demo directory shows how filters are set up, how data is processed sample by sample and how the frequency responses look like with the help of python scripts.
Impulse responses and spectra of different filters:
./iirdemo
python3 plot_impulse_fresponse.py
50Hz removal and lowpass filtering:
./ecg50hzfilt
python3 plot_ecg_filt.py
Optimisation tips
The actual filter operations are header-only which means that they will never be pre-compiled in the library but the compiler can optimise the filter routine for your local processor. Consider using:
add_compile_options(-O3 -march=native)
