Megjegyzések:	DFT is one of the most common signal processingtasks. A resonator based observer has been proposed by G. Péceli to recursively calculate the DFT, with the added bonus that the sampling frequency does not need to be exactly matched to the fundamental frequency of the periodic signal as it is the case for DFT (signals fundamental frequency needs to be on DFT grid, else we face leakage and picket fence effects). Resonator based observer requires the knowledge of the fundamental frequency. F. Nagy suggested using the resonator based observer to measure the frequency mismatch from the current knowledge of it, and adapt the resonator positions based on this measurement (Adaptive Fourier Analyzer). In this paper we summarize different frequency adaptation techniques of the resonator positions already published in the literature, and propose a new robust algorithm for that.
