Fig. 3.5 Principal scheme of the decision-making system based on the sequential analysis
procedure. A description of the sub-units is given in Table
3.1
In these cases, the sequential procedure will
finish with the probability equal to 1
if the following conditions are satis
ed:
(1) E

The probability of completion of the procedure is small when one of the
following conditions is not satisfied:

Unit VMD coordinates system input with the separate channels of measured
data. As each random process {x
i
} is executed, analyses are carried out to eliminate
errors and to represent input signals in a form that is acceptable for the other units.
The unit CSC calculates signal characteristics:
