| Abstract(in English) | An averaged power spectrum, which is calculated from two power spectra using two time windows a half pitch-period apart, does not depend on the relative phase between the analyzed signal and the windows. This article introduces a procedure to calculate instantaneous frequency, which yields temporally static representation of the instantaneous frequency of periodic signals. The proposed method is derived from the famous Flanagan's equation. Specifically, a power weighted average of instantaneous frequencies, which are calculated using the Flanagan's equation, yields this temporally static representation. A proof of the independence of the proposed representation on the relative phase between the analyzed signal and the windows is presented assuming weak conditions on the windowing function. Performance evaluation tests are conducted for popular windowing functions and their results are discussed. |
