In order to determine spectral and/or periodic portions in a sequence of data (d(n)) containing binary values (0; 1) at a number (N) of position numbers (n), the data sequence (d(n)) is evaluated by position number at discrete evaluation points (m) with a complex analysis function (f(n, m)). To this end, to form a complex binary analysis function (BA(n, m)) on the complex analysis function (f(n, m)), a comparator function (k) is used in accordance with the prescription: k (f(n, m)) = + 1 for f(n, m) > (S); k (f(n, m)) = - 1 pour f(n, m) < (S); k (f(n, m)) = - 1 or + 1 for f(n, m) = (S); with (S): as the threshold value within the range of values of the analysis function (f(n, m)). The values (0, 1) of the data sequence (d(n)) are then multiplicatively concatenated with the binary values (-1, +1) of the binary analysis function (BA(n, m)) allocated to them and the sum of the results of concatenation (QS) is formed and evaluated for at least one evaluation point (m). |
