HERNANDEZ-BALBUENA, D.  y  TYRSA, V.E.. Método para la medición de frecuencia usando aproximaciones racionales. Rev. mex. fis. [online]. 2006, vol.52, n.4, pp.359-364. ISSN 0035-001X.

An alternative method for frequency measurement of highly stable oscillators based on the direct comparison of frequencies, the use of rational approximation, and the Archimedean property of the real numbers is presented. This method allows figure out a level of measurement uncertainty comparable in magnitude to the frequency uncertainty of an atomic oscillator in a very short amount of time. Simulation results based on the mathematical model of the proposed method are presented.
