Abstract :
The use of Cosine transform to analyze the model-noise pattern alteration withdifferent vibration model applied on multimode fiber optics are studied. It s results comparedwith the Fourier transform to perform the same analysis using total frequency difference andthe computation time, which almost coincide for the both transforms. A discussion for theresults and recommendation are introduced.
