<p>The method involves evaluating signals (10) to be analyzed concerning to occurrence of maximum and/or minimum values (21, 22), by considering determined number (11) of values in an evaluation section of the signals. The maximum and/or minimum values are filtered by low pass transfer functions (31, 41) with time constants (32, 42), and the maximum and/or minimum values are reprocessed by differentiation of amplitude value (51), where the amplitude value is evaluated for analyzing oscillations of the signals. The amplitude value is filtered by a third low pass transfer function (61). An independent claim is also included for a diagnosing device for detecting oscillations of signals.</p> |
