complete unbalance)
40
In case that the filter response exactly matches the user-defined gain factors
In case that the user-defined gain factor is set below 3. The tolerance increases, if the gain factor is larger.
41
In case that the user-defined gain factor is set below 7. The tolerance increases, if the gain factor is larger.
42
43
In case that the user-defined gain factor is set below 7. The tolerance increases, if the gain factor is larger.
