DiFi++ is a small c++ header-only library for **DI**gital **FI**lters based on rational transfer functions such as the butterworth filter and the moving average filter. DiFi++ is using the Eigen library for math computations.
|
|
|
|
The implementation is based on well written article from Neil Robertson.

The library has been tested against Matlab results.
|
|
|
|
A doxygen documentation is generated when compiling.

Installing
|
|
-----
|
|
|
|
This is an header-only library so there is nothing to compile (but the documentation)
|
|
|
|
```bash
|
|
git clone --recursive https://github.com/vsamy/DiFi++
|
|
cd DiFi++
|
|
mkdir build
|
|
cd build
|
|
cmake ..
|
|
make install
|
|
```
|
|
|
|
Note
|
|
-----
|
|
The method used is close but somewhat different from Matlab methods and Butterworth band-reject has quite different results (precision of 1e-8). |
