| Name | Description |
|---|---|
| BesselBaseCoefficients | Return coefficients of normalized low pass Bessel filter (= gain at cut-off frequency 1 rad/s is decreased 3dB) |
| toHighestPowerOne | Transform filter to form with highest power of s equal 1 |
| normalizationFactor | Compute correction factor of low pass filter such that amplitude at cut-off frequency is -3db (=10^(-3/20) = 0.70794...) |
| bandPassAlpha | Return alpha for band pass |
