The user enters a value, which is adjusted to the closest central frequency. The bandwidth between Lower and Upper central frequency must be lower than or equal to eleven filters (considering octave bands) and 31 filters (considering 1/3 octave bands). So, if this bandwidth increases, then the Lower central frequency is automatically increased. | The user enters a value, which is adjusted to the closest central frequency.

'''Note:''' For having the last band compatible with the Class #1 standard, the front end sampling frequency need to cover the full band. Exemple: for having Class #1 compatible for 1/3 octave 20kHz the sampling frequency need to be 65,536kS/s. If you let the sampling frequency at 51.2kS/s (20kHz bandwith) you will be Class #2 standards. | |||
