removal, a series of data transmission system.  It is natural to assume that condensation of the channels and functions in such a system reaches a high level.  We are only concerned with the most primitive of them.

       Finally the third question which concerns the code structure, i.e., the semantic irregularities of the EEG in the broad sense, has been studied less than anything.  Any conceived disturbances in the activity of any one of the indicated sides of functioning of the system can be represented as pathology.  Thus, a insufficiently precise detection and tracking of the source of information causes for the correspondent possibly, the same deep disorder, as does the absence of proper synchronizing or short duration failures in coding and decoding.  Thus far questions connected only with rhythmics and synchronizing have been studied.

1.  Detection of the Central Frequency  ƒ(0)

       Let us suppose there is an infinite system of signals, the average
frequencies of which are constant and are determined by the set

0,  . . . ,  f_−t,  . . . ,  f_−n−1,  f_−n,  f₀,  f_n−1,  f_n,  . . . ,  f_k,  . . . , ∞.

moreover

                        f_{−n−1 <} f_{−n <} f_−n+1,  f_{n−1 <}  f_{n <}  f_n+1                         (1)

       We accept the fact that the function  f(n) is monotone, and further-
more, it possesses the following property:

                                      f (n) f (−n) = f ² (0)                                    (2)

       If the bands of frequencies ∆ f_n are symmetric with respect to average frequencies f_n and they are in contact with the bands of frequencies ∆ f_n−1 and ∆ f_n+1, but nowhere do they cut each other in the interval of frequencies (0, ∞), that corresponds to the interval of the ordinal numbers of the signals (−∞, +∞), then the width of the band ∆ f_n  can be expressed by the formula
