Zizindikiro zovomereza zitha kugawidwa muzizindikiro za mphamvundizizindikiro za mphamvumalinga ndi mphamvu zawo.Zizindikiro za mphamvu zimatha kugawidwa m'magulu a periodic ndi ma aperiodic sign molingana ndi nthawi kapena ayi.Chizindikiro cha mphamvu chimakhala chochepa mu matalikidwe ndi nthawi, mphamvu zake zimakhala ndi malire, ndipo mphamvu zake zapakati (panthawi yochuluka) ndi ziro.Kutalika kwa chizindikiro cha mphamvu ndi chopanda malire, choncho mphamvu zake zimakhala zopanda malire.
Makhalidwe a siginecha inayake amatha kuphunziridwa mu ma frequency domain komanso nthawi yanthawi.
Palimitundu inayi ya chizindikirokatundu mu frequency domain: spectrum, spectral density, energy spectral density and power spectral density.Mawonekedwe amtundu wa chizindikiro champhamvu cha periodic amatha kuyimiridwa ndi mndandanda wa Fourier, ndipo zinthu zomwe zili mndandandawu zimapanga mawonekedwe amtundu wa chizindikiro, ndipo gawo lake ndi V. Mawonekedwe a chizindikiro cha mphamvu akhoza kuimiridwa ndi kusintha kwa Fourier, ndi ntchito yopezedwa ndi kusintha kwa ma waveform ndi The spectral density of sign, unit yake ndi V/Hz.Malingana ngati ntchito yokakamiza ikuyambitsidwa, titha kupezanso kachulukidwe kake ka chizindikiro cha mphamvu.Kachulukidwe kakachulukidwe ka mphamvu ndi kugawa kwamphamvu kwa siginecha yamagetsi mumayendedwe pafupipafupi, ndipo gawo lake ndi J/Hz.Mphamvu ya spectral kachulukidwe ndi kugawa kwa mphamvu ya siginecha yamagetsi mumayendedwe pafupipafupi, ndipo gawo lake ndi W/Hz.
Zimadziwika kutimawonekedwe a chizindikiromu nthawi yoyang'anira nthawi makamaka imaphatikizapo ntchito yolumikizirana yokha komanso yolumikizirana.Ntchito ya autocorrelation imawonetsa kuchuluka kwa kulumikizana pakati pa zikhalidwe za siginecha nthawi zosiyanasiyana.Ntchito ya autocorrelation R (0) ya chizindikiro cha mphamvu ndi yofanana ndi mphamvu ya chizindikiro;ndi autocorrelation ntchito R (0) ya siginecha yamphamvu ndi yofanana ndi mphamvu yapakati pa siginecha.Ntchito yolumikizirana ikuwonetsa kuchuluka kwa kulumikizana pakati pa zizindikiro ziwirizi, zomwe sizidalira nthawi komanso zimangogwirizana ndi kusiyana kwa nthawi, ndipo ntchito yolumikizirana ikugwirizana ndi dongosolo lomwe zizindikiro ziwirizi zimachulukitsidwa.Ntchito ya autocorrelation ya siginecha yamphamvu ndi kachulukidwe kake kamphamvu kamene kamapanga matembenuzidwe a Fourier.The autocorrelation ntchito ya periodic mphamvu chizindikiro ndi mphamvu sipekitiramu kachulukidwe kupanga awiriFourier amasintha.Ntchito yolumikizirana ya chizindikiro cha mphamvu ndi kachulukidwe kake kakang'ono ka mphamvu kamene kamapanga mitundu iwiri ya Fourier.Kulumikizana kwamphamvu kwa nthawi ndi nthawi komanso kuchuluka kwa mphamvu zake kumapanga masinthidwe a Fourier.
Chizindikiro chotsimikizika ndichidule chachidule chomwe chili pamwambapa.Ndikukhulupirira kuti nkhaniyi ikuthandizani kuti muwonjezere chidziwitso chanu.Kupatula nkhaniyi ngati mukuyang'ana kampani yabwino yopanga zida zoyankhulirana zama fiber zomwe mungaganizirezambiri zaife.
