Abstract：There is no precious formula in textbooks and literatures for the concrete frequency after digitalizing the continuous signals higher than Nyquist frequency, although algorithms have been given in some literatures, there was no precision and without physical meaning. For that reason, the paper uses geometric model having physical meaning to solve precise computational formula, which is suitable for the people realizing the relationship between the sampling and frequency more straightforwardly.
