rhythm refer to the yearly rhythms, the longest go beyond the limits of the necessary. That fact, that in this case in organism all components can be utilized, should not astonish us. Experimental observations over EEG rhythms (minute and hourly) show that separate rhythms are split, show themselves partially, or are temporarily completely absent. The picture drawn above of rhythms is steady only in the statistical plan.
With frequency interpretation of biological rhythms functional restraints are not applied to the amplitudes of separate rhythms or to their average values.
It is another matter if the discussion concerns the length of clipped signals. In this case the amplitude of the rhythms should monotonically and very definitely grow with the increase in the period. Otherwise the length of the time intervals of a clipped signal will become constant under some conditions.
There is experimental confirmation of the fact that the square of the average amplitude of an alpha-rhythm is equal to the product of the squares of the amplitudes of equidistant rhythms . Considering the results of work , one can assume, that the average values of the amplitudes of EEG rhythms change depending on the ordinal number of rhythm according to the law
where k - a coefficient, the value of which lie within the limits 0.8 - 1.2.
It is known that variable voltages of an EEG are observed in the background of constant voltages, the size of which can exceed the amplitude of EEG-waves by 10 thousand times. Assuming the average value of the amplitude of an alpha-rhythm equal to 10 μV we find that at k = 1 the value of the amplitude of the 11th rhythm will be equal to 50 μV. This result will not contradict the observations.
