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.
