%X A novel method based on the analysis of instantaneous phase was proposed to extract the fitter on clock signals. I}he method utilizes the Hilbert transform to extend the real signal of clock into an analytic signal, and the implementation of Hilbert transform is based on the Fourier transform windowed with two window functions. Then, the fitter of clock is extracted from the instantaneous phase of analytic signal. The experimental results for a fitter signal present that the proposed method can effectively extract the fitter on clock signals and has better precision than other methods.
