The IPA modules each provide a parameter module for the time range and the frequency range (frequency analysis).
(a) For the time range, the parameter module includes numerous special mathematical functions. Here, the mathematical understanding of the user is especially asked for when it comes to the selection of functions that could be used in a practical case. During which practical problem respectively example would you use e.g. the function "standard deviation" or "median"? Does anything speak against selecting as many functions as possible to guarantee those pattern- information filtered out you might not see in the first place??
(b) The use of the parameter module for the frequency range requires a special physical understanding in practical appliance. Please name some case studies in this context and try to find a generalizing statement to its use.
