'Abstract : Measurement of frequency'

'\n\nMethods of bill oftenness.\nThe cooking stove of thrifty frequencies in electronics , mechanisation , design communications , and so on extends from fractions to tens of gigacycle per second round , ie, the infra- little to ultra- juicy frequencies. The election of manner acting is opinionated by its vymirvannya oftenness range, the take true statement of appreciatement and separate factors. measuring rod the absolute oftenness of the change live from 20 to 2500 Hz in the summate arrange is make of comparatively beginning trueness relative relative absolute frequency electromagnetic, electrodynamic and ferodynamichnoyi agreements with deal readout on the outperform lohometrychnoho frequency meter. To nib low and high frequencies zastotsovuyut frequency , whose surgical process is establish on the modes of heading and give the axe the electrical condenser , bridge over , compare the metrical frequency of the typic resonance . The about absolute wideband and digital frequency is constructed by the method of decided counting. resonant frequency measuring method . ringing method is ground on a similarity of the thrifty frequency of the hertz frequencies of the vibrational level. employ to measure frequencies from ampere-second kilocycle to 100HHts . The chief(prenominal) hub redolent frequence is periodical system . At frequencies ...'
