Fa'ailoga filifili ma le puleaina o le malosi: lua ituaiga taua o analog chip

O oloa filifili faʻailoga, lea e masani ona aofia ai faʻamalosi faʻatinoga ma faʻaliliuga faʻamaumauga, faʻatautaia manaʻoga o fesoʻotaʻiga faʻamatalaga.I totonu o se faiga fa'akomepiuta-i-analog fa'afefiloi, o le fa'agasologa atoa o fa'ailoga e fa'apea.

Sensors: O faʻailoga faʻaletino mataʻutia mai le lalolagi i fafo, e masani lava o leo, ata, vevela, susu, mamafa, ma isi, e maua e masini ma liua i faʻamaufaʻailoga faʻasolosolo taimi e fetaui ma nei faʻailoga faaletino, e masani lava i foliga o le voltage / taimi nei.

Amplifiers ma filiga: O faʻamaufaʻailoga analog e faʻatautaia e iunite faʻamaonia faʻailoga e aofia ai faʻamalosi ma filiga.O le mea fa'atele e fa'atuputeleina fa'ailoga analog laiti ma vaivai e fa'afetaui i latou i le fa'aogaina atoa o le ADC;o le faamama e masani lava ona fa'agata le fa'ailo e fa'amalieina mana'oga o le fa'ata'ita'iga a Nyquist.

Fa'aliliuga fa'amaumauga: fa'aliliuina e le ADC le fa'agasologa o le voltage/fa'ailoga o lo'o i ai i le aofa'i fa'afuainumera tu'ufa'atasi, lea e tu'uina atu i le iunite fa'akomepiuta mulimuli ane mo le gaosiga.

Fa'atonuga fa'afuainumera: O numera fa'afuainumera tu'ufa'atasi e fa'afuainumera e se faiga fa'akomepiuta (MCU, DSP, po'o le FPGA), lea e masani ona fa'aogaina e fa'atino ai fa'asologa o fa'ailoga fa'akomepiuta algorithms.

Fa'aliliuga fa'amaumauga: O le aofa'i fa'afuainumera tu'ufa'atasi pe a mae'a ona fa'agaoioia e le faiga fa'akomepiuta e tu'uina atu i le DAC, lea e toe fa'aliliuina ai i se fa'ailo fa'asolosolo fa'asolosolo.

Filifiliga: Talu ai o le faʻailoga o le DAC o loʻo i ai vaega o le "laasaga" maualuga, e faʻaaogaina se faamama toe faʻaleleia e faʻamama ai le pisapisao maualuga, e mafua ai le toe faʻaleleia o le faʻailoga analog.

O le mea pito sili ona taua o nei mea o le faʻaogaina o le amplifier ma le faʻaliliuga faʻamatalaga.

O faʻamalosi faʻatinoga o "poloka faʻavae autu" o taʻaloga analog ma faʻaaogaina i le tele o faʻaoga.O fa'amalosi fa'agaioiga o ta'amilosaga fa'aopoopo e fa'aopoopo ma tu'ufa'atasia fa'ailoga analog ma e masani ona fa'aogaina e fa'ateleina ai fa'ailoga laiti ma vaivai i fa'ailoga tetele.I le taimi lava e tasi, o faʻamalosi faʻagaioiga o le faʻavae lea mo le tele o masini analog, e pei o numera-i-analog converters, suiga o loʻo i ai nei-i-voltage, filiga, faʻatusatusa, ma faʻatonutonu laina.E mafai ona faʻapea o faʻamalosi faʻatinoga o "poloka faʻavae autu" o taʻaloga analog.

O fa'aliliuga fa'amaumauga o le alalaupapa lea i le va o faiga fa'akomepiuta ma fa'aoga numera ma e mana'omia.O le analog-to-digital converter (ADC) e nafa ma le faaliliuina o faailoilo analog i faailoilo numera ma le numera-i-analog converter (DAC) e nafa ma le faaliliuina o faailo numera i faailoilo analog.O masini e fa'aliliuina le vevela o le lalolagi moni, omiga, leo, ma isi i fa'ailo eletise, o le tele lava o fa'ailoga analog ma e le mafai ona iloa ma fa'agaoioia e faiga fa'akomepiuta.E na'o le liua e le ADC e mafai ai ona pu'eina ma fa'agasolo e le MCU.E le gata i lea, e manaʻomia e failauga, ma isi mea faʻaoga faʻailoga analog e galue ai, o lea e manaʻomia ai DACs e faʻaliliuina ai faʻailoga numera e faʻaogaina e le masini numera i faʻailoga analog.O le mea lea, so'o se taimi e a'afia ai fa'agaioiga fa'atekinolosi, e tatau ona iai se fa'aliliuga fa'amaumauga.

Op-amps o le faavae mo le tele o masini analog, mo se faʻataʻitaʻiga, o filiga e faia i op-amps ma resistors.

O fa'aliliuga fa'amatalaga e aofia ai fa'aliliuga fa'akomepiuta-i-analog (DACs) ma fa'aliliu fa'aigoa-i-numera (ADCs)

O le puleaina o le malosi o se mana'oga mo ta'avale eletise.Afai lava e manaʻomia e se faiga faʻaeletoroni se faʻaogaina o le eletise, e masani ona faʻapipiʻiina le eletise, maa, ma isi. Faʻalagolago i le ituaiga o faʻaogaina ma le gaosiga o loʻo i ai nei, e mafai ona tatou faʻavasegaina pule o le eletise i ituaiga autu e 4: AC-DC (rectifier), AC -AC (inverter, ma isi), DC-DC (chopper), ma DC-AC (inverter).

Suiga fa'asa'o (AC-DC) e nafa ma le fa'aliliuina o le mana AC i le mana DC ma e masani lava ona maua i fa'aoga eletise mo komepiuta feavea'i.

AC-AC converters (AC-AC) e nafa ma le faaliliuina o se taimi patino o le mana AC i se isi taimi faifai pea pe fesuisuiai o le mana AC.

O le DC-DC converter (DC-DC) fa'aliliuina le mana DC i se isi mana DC fa'atasi ai ma fa'asologa eseese, vaega, taimi nei, ma uiga voltage.

Inverters (DC-AC) sui converters e faaliliu ai le mana DC i le mana AC, o nisi e taʻua i latou o converters, ma o vaega autu ia o le faʻaogaina o le eletise eletise ma sapalai eletise e le motusia (UPS).

O tupe meataalo pulea o loʻo tuʻufaʻatasia le pulega o le eletise o latou galuega autu o le faatonutonuina o le voltage, faʻaleleia o le voltage, faʻaauau pea, AC-DC liua, ma isi. Ua vaevaeina i latou i le laina eletise eletise (LDO), pamu-pamu (Charger-pump) meataalo, DC -DC converters (DC-DC), AC-DC converters (AC-DC), LED avetaʻavale meataalo, ma isi mea masani o loʻo faʻapipiʻiina ma avetaʻavale LED mo tagata faʻatau e pei o telefoni feaveaʻi ma komepiuta api.Mo se fa'ata'ita'iga, e tu'u i lalo e le au fa'atonu eletise le eletise autu o le 220V ma fa'aulu mai se DC mautu eletise maualalo mo le fa'aoga i komepiuta api;E fa'atupuina e aveta'avale LED le sapalai o le eletise i totonu o telefoni fe'avea'i e fa'amomomo meapueata.
