The paper presents the most important key dates of the history and the development of the Frequency Domain Methods in Experimental Modal Analysis. First, the mathematical foundations are discussed, then the Phase Resonance Method is presented, and finally the different algorithms of Frequency Domain Phase Separation Methods are considered. They start with the SDOF Methods followed by the MDOF Methods in the form of Forced Response Modal Methods and FRF Modal and Polynomial Methods, completed by the recent developments and trends of Frequency Domain Modal Identification Methods.
