FIR band-stop filtering (FFT implementation).
Ilustrates WaveWarp's FIR filtering (FFT implementation) (in this case, a band-stop design). The filters are designed
"on-the-fly" by a variety of methods or can be read in from ascii files (e.g. generated by MATLAB).
The highly efficient FFT implementation in this example is required for filter lengths above 100 or so. [Compare with the
"FIRfilteringDirectExample4.dwb" DrawingBoard for an example of an FIR band-stop filter implemented directly.]
