Review of spectral analysis algorithms was done. Spectral analysis with additional algorithm allows to determine the mechanical resonance frequency of multi-mass system. Determination of resonance frequencies allow for proper tune the digital filter. This paper presents selected algorithms of determine signal spectrum. In order to determine the mechanical resonance frequency from the whole spectrum, it is require to use an additional algorithm that was omitted from the consideration. The algorithms were implemented for the digital signal processor SHARC family. Proposed algorithms were implemented in C and using complex data structures in C++. The use of C++ allows for the simplification of the program. The algorithms were compared in terms of computational complexity and memory usage.
