Configuration parameters
- Calculate SamplesToFilter automatically: Is a boolean value that indicates whether SamplesToFilter should be calculated automatically.
- SamplingRate: sampling rate fs in Hz (greater than zero).
- Cutoff: cut-off frequency in Hz (greater than 0 and less than SamplingRate/2).
- SamplesToFilter: number of samples for calculating the sliding average value (often referred to as window size).
- Initial Values (optional): initial values define the internal state of the filter.
