Way of achieving the desired value generator periodic frequency stability (including pure sine wave) signal generator using a frequency periodic (including sinusoidal) signal of the same nominal frequency value, but lower values ​​of stability

摘要

Method achieve periodic signal generator frequency required value stability when using periodic generators (including sinusoidal) signal with the same value of the nominal frequency, but with lower values ​​of stability, characterized in that use a recursive approach, namely, is performed next in order to achieve the desired value sequence of steps: taken 2 independent generator uncorrelated with the output periodic signals with equal or similar values ​​prefecture inalnyh output frequencies and equal or close values ​​of frequency stability, the signals from which are fed to the multiplier signals (in the case of sinusoidal periodic signals - directly, and in the case of other forms of periodic signals - through a bandpass filter tuned to the rated frequency) after which the signal output from the multiplier is supplied to high-pass filter that passes twice the nominal frequency and the impermeable lower (difference) frequency of the output signal of which, in turn, often fed to the divider s is 2, the signal output from the high-pass filter is supplied to a bandpass filter that passes only a nominal frequency (first harmonic of a periodic signal); thus obtained set of the above devices is declared generator with the new received higher stability at once higher stability starting generators and, if the stability of frequencies below the sought, then going to another of the same generator and, through the use of two new generators performed the above-described sequence of steps and so on until, until the
