Algorithm details for parametrization purposes


Some parameter detection algorithms require a special parametrization. Additionally some algorithms like filters, are only used for preprocessing to smooth very noisy signals in order to receive no noise affected respiratory parameters. Some background information about the respective algorithms is given below.


In the calculation of respiratory parameters like the breath detection e.g., filters are used to handle noisy input signals.

Filtering algorithms

Filtering algorithm as well as their parametrization have to be chosen with care.

A simple filter is the averager ("Averager") and a more advanced filter, especially for very noisy signals (also with high frequency noise) is the Savitzky-Golay filter ("Savitzky-Golay filter").
