Abstract : Measurement of frequency

\n\nMethods of measuring frequency.\nThe carry of bank noted frequencies in electronics , automation , engineer communications , etcetera extends from fractions to tens of giga cycle per second hertz , ie, the infra-low to ultra- naughty frequencies. The choice of order is determined by its vymirvannya frequency range, the call for true statement of beat and other factors. step the frequency of the change current from 20 to 2500 Hz in the supply string is made of comparatively low accuracy oftenness electromagnetic, electrodynamic and ferodynamichnoyi carcasss with govern readout on the outmatch lohometrychnoho frequency meter. To measure low and high frequencies zastotsovuyut frequency , whose performance is base on the manners of charge and swing the capacitor , link up , comparing the heedful frequency of the emblematical resonance . The around accurate broadband and digital frequency is constructed by the method of discrete counting. resonant frequency me asure method . plangency method is based on a comparison of the mensural frequency of the cycles/second frequencies of the vibrational level. apply to measure frequencies from vitamin C kHz to 100HHts . The important hub Resonant Frequency is oscillatory system . At frequencies ...
