Imiqondiso yokuvuma inokwahlulwa ibeiimpawu zamandlakwayeiimpawu zamandlangokwamandla abo. Imiqondiso yamandla inokwahlulwa ibe yimiqondiso yamaxesha athile kunye nemiqondiso ye-aperiodic ngokungqinelana nokuba ngaba ngamaxesha athile okanye hayi. Umqondiso wamandla unomda kwi-amplitude kunye nobude, amandla ayo anomda, kwaye amandla awo aphakathi (ngaphezu kwexesha elingapheliyo) ngu-zero. Ubude bexesha lomqondiso wamandla abunasiphelo, ngoko ke amandla ayo angenasiphelo.
Iimpawu zesignali ethile zinokufundwa kuzo zombini i-domain frequency kunye ne-time domain.
Naziezine iintlobo zomqondisoiipropathi ezikwi-frequency domain: i-spectrum, ingxinano ye-spectral, ingxinano ye-spectral yamandla kunye noxinano lwamandla. I-waveform ye-periodic power signal inokumelwa yi-Fourier series, kwaye izinto zoluhlu zenza i-spectrum ye-discrete ye-signal, kwaye iyunithi yayo yi-V. I-waveform yesignali yamandla inokumelwa yi-Fourier transformer, kwaye umsebenzi ofunyenwe ngoguqulo lwamaza yi-spectral density yesignali, iyunithi yayo yi-V/Hz. Ngethuba nje umsebenzi wempembelelo kwaziswa, sinokufumana kwakhona ubuninzi bayo be-spectral yomqondiso wamandla. Ubuninzi be-spectral yamandla kukusasazwa kwamandla omqondiso wamandla kwi-frequency domain, kwaye iyunithi yayo yi-J/Hz. Ubuninzi bembonakalo yamandla kukusasazwa kwamandla esignali yamandla kwi-domain frequency, kwaye iyunithi yayo yi-W/Hz.
Kuyaziwa ukubaiimpawu zomqondisokwi-domain yexesha ikakhulu ibandakanya umsebenzi wokudibanisa ngokuzenzekelayo kunye nomsebenzi wokudibanisa. Umsebenzi we-autocorrelation ubonisa iqondo lokuhambelana phakathi kwamaxabiso omqondiso ngamaxesha ahlukeneyo. Umsebenzi we-autocorrelation R (0) wesiginali yamandla ilingana namandla ophawu; kunye nomsebenzi wokulungelelaniswa kwe-autocorrelation R (0) yesiginali yamandla ilingana nomndilili wamandla ophawu. Umsebenzi we-cross-correlation ubonisa iqondo lokudibanisa phakathi kweempawu ezimbini, ezizimeleyo kwixesha kwaye zihambelana kuphela nokwahlukana kwexesha, kunye nomsebenzi wokudibanisa umnqamlezo uhambelana nomyalelo apho izibonakaliso ezimbini zandiswa. Umsebenzi wokulungelelaniswa kwe-autocorrelation yesiginali yamandla kunye noxinaniso lwamandla okubonwayo lwenza iperi ye-Fourier transforms. Umsebenzi we-autocorrelation yesiginali yamandla ngamaxesha kunye noxinaniso lwamandla okubonwayo lwenza iperiUFourier uyatshintsha. Umsebenzi wonxulumano olunqamlezileyo lomqondiso wamandla kunye noxinaniso lwembonakalo ye-energy enqamlezayo lwenza iperi ye-Fourier transforms. Umsebenzi wonxulumano wophawu lwamandla ngamaxesha athile kunye ne-spectrum yamandla anqamlezayo enza ipere ye-Fourier transforms.
Isiginali eqinisekisiweyo yintshayelelo emfutshane engentla. Ndiyathemba ukuba eli nqaku linokukunceda ukwandisa ulwazi lwakho. Ngaphandle kweli nqaku ukuba ujonge inkampani elungileyo yomenzi wezixhobo zonxibelelwano lwefiber onokuthi uyithathele ingqalelongathi.
