The paper illustrates a fundamentally different approach applied to Blade Tip-Timing analysis in the background of works performed through the long history of this method. New innovative approach is based on the precise separation of measured data that was published in previous works. In this respect, the construction of the signal profile is intended for fast and accurate definition of the regulation function served to expression of the complete speed fluctuation and its instabilities. Following, the presented signal profile is demonstrated on four variants of data processing in two significantly different operations, where it allows the application of a one-step approach. Finally, these results are also compared with a two-step method used in previous cases without the signal profile. The benefit of the suggested procedure of the signal profile calculation is evident in the possibility of processing more complex functions in deterministic methods without limiting the characteristic advantages of these methods.
