Abstract
There are frequency and amplitude errors in spectrums obtained from discrete spectrum analysis to windowed signals. In this paper, the discrete spectrum correcting technology based on centroid method is proposed. The deduction of correction formula applying to Hamming window function, Blackman window function, and Kaiser window function are putted forward. The validity of the formulas is testified through the simulation on Matlab and Labvindows/CVI.
