摘要
According to the invention, a method for estimating the fundamental frequency of a harmonic signal comprises the steps: - forming a fundamental frequency hypothesis (f0'); - providing a comb filter based on the fundamental frequency hypothesis; - filtering the harmonic signal using the comb filter; and - testing the fundamental frequency hypothesis for each tooth in the comb filter.
