Zusammenfassung: | For the dual-mixer time-difference method using the discrete Fourier transformation, the formulation of the truncation error to determine the time difference between two oscillators is derived. It is found that serious error occurs due to the truncation error with a larger frequency difference between two oscillators. The condition of the discrete Fourier transformation to determine the frequency difference between two oscillators with sufficiently high accuracy for atomic clocks is obtained. |
