A filter based on the fuzzy logic technique to enhance the signal‐to‐noise ratio of Raman spectra is presented. The reasoning for generating a fuzzy filter is explained and its performance is evaluated on Raman spectra contaminated with cosmic ray events and shot noise. The filter suppresses noise and simultaneously preserves information without requiring a priori knowledge on the accurate shape of the Raman band and on the statistics of the noise that masks the information signal.
