A small C++17 template-based library that provides various useful classes for digital signal processing.
To use this library, simply add include/ to your include directory paths.
You can also use this repository as a Meson subproject.
See examples/ for various examples.
The following table presents the available functor classes in this library.
| Category | Class | Description |
|---|---|---|
| Filter | dsp::filter::convolution |
Convolution-based filter. |
dsp::filter::recursive |
Recursion-based filter. | |
dsp::filter::chebyshev::low_pass |
Chebyshev digital filter (experimental). | |
dsp::filter::chebyshev::high_pass |
Chebyshev digital filter (experimental). | |
dsp::filter::windowed_sinc::low_pass |
Windowed-sinc digital filter. | |
dsp::filter::windowed_sinc::high_pass |
Windowed-sinc digital filter. | |
dsp::filter::moving_average |
Fast moving average digital filter. | |
dsp::filter::all_pass |
Placebo digital filter. | |
| Misc. | dsp::derivative |
Derivate the input signal. |
dsp::integral |
Integrate the input signal. | |
dsp::pid |
