Unstable leading multipliers

Results of the Discriminant Analysis. For each of the two set-ups, the following parameters were used peak maximum, onset temperature, heat necessary to melt the unstable, P and p crystals (absolute and relative values). This leads to eight parameters per storage time, which, multiplied by four storage times (0, 1, 4, and 24 h after production), leads to 32 parameters per individual. However, some parameters failed the tolerance test. This means that for that parameter the variance within a group was too big compared to the variance between the groups. These parameters were left out because they would not increase the prediction quality. 

The low-pass filter assoeiated with die multiplier eonsists of an RC unit with the time constant equal to 300 ms. Two neeessary eonditions dietate the choice of the time constant. First, a very long duration results in a long reaction time of the galvanometer needle, whieh may lead to the risk of not being able to deteet the coneurrenee. Seeond, too short a duration does not allow filtering out effeetively the radio-frequency parasites, at whieh point the galvanometer needle beeomes unstable and vibrates excessively.
