I-Digital Power Amplifier kunye ne-Analog Power Amplifier ziintlobo ezimbini eziqhelekileyo zee-amplifier ezibonisa umahluko owahlukileyo ekukhuliseni nasekucutshungulweni kwesignali yesandi. Eli nqaku liza kwazisa imigaqo esisiseko kunye nomahluko ophambili phakathi kwezi-amplifier zimbini, linike abafundi ulwazi malunga nokusetyenziswa kwazo kwiinkqubo zesandi.

1. Imigaqo

Isandisi-mandla seDijithali: I-Digital Power Amplifier isebenzisa itekhnoloji yeDigital Signal Processing (DSP) ukuguqula imiqondiso yesandi ibe yifomathi yedijithali kunye nokuzikhulisa nokuzicwangcisa kwicandelo ledijithali. Ngokwesiqhelo ibandakanya ii-Analog-to-Digital Converters (ADC) kunye neeDigital-to-Analog Converters (DAC) ukuguqula imiqondiso yesandi ye-analog ibe yimiqondiso yedijithali ukuze icutshungulwe kwaye ibuyiselwe kwimiqondiso ye-analog ukuze iphume.

Isandisi-mandla soBugcisa se-E Series

Isandisi-mandla se-Analog:I-Analog Power Amplifier yandisa ngokuthe ngqo isignali yesandi se-analog yokufaka, isebenza ngendlela efanayo nee-amplifier zemveli. Yandisa isignali yokufaka ukuya kwinqanaba lamandla elifunekayo kwaye ikhuphe isignali ye-analog eyandisiweyo nge-output port yayo.

2. Ichanekilei-ionkunye nokugqwetheka

Isandisi-mandla seDijithali:IiDijithali Power Amplifiers zinobuchule obuphezulu ngexesha lokucubungula isignali yedijithali, nto leyo evumela ulawulo oluchanekileyo lokufumana isignali yesandi kunye nempendulo yamaza amaninzi. Ngenxa yokuchaneka kokucubungula isignali yedijithali, ii-digital power amplifier zihlala zibonisa ukuphambuka okuphantsi kunye nengxolo.

Isandisi-mandla se-Analog:Ii-Analog Power Amplifiers zizisa inqanaba elithile lokuphambuka kunye nengxolo ngexesha lenkqubo yokukhulisa, ngokuyintloko ngenxa yeempawu ezingezizo ezithe ngqo zeesekethe ze-analog. Nangona ii-analog power amplifier zanamhlanje zenze inkqubela phambili enkulu, amanqanaba azo okuphambuka ngokubanzi aphezulu xa kuthelekiswa.

3. Ukusebenza kakuhle

Isandisi-mandla seDijithali:IiDijithali Power Amplifiers zisebenza kakuhle kakhulu kuba inkqubo yokuguqula amandla inciphisa ukulahleka kwamandla kwicandelo ledijithali. Zinokugcina ukusebenza kakuhle okuphezulu nokuba zinomthwalo ophantsi.

Isandisi-mandla se-Analog:Ii-Analog Power Amplifiers zihlala zisebenza kancinci, njengoko zivelisa ukulahleka kobushushu namandla ngexesha lokukhulisa. Ukusebenza kakuhle kudla ngokuncipha ngakumbi kwii-analog power amplifier xa amandla ephuma phezulu.

4. Ukuguquguquka kunye nokulungelelanisa-ubuchule

Isandisi-mandla seDijithali:IiDigital Power Amplifiers zinokufezekisa imisebenzi emininzi kunye neempawu ezihlengahlengiswayo ngokusebenzisa isoftware programming. Zihlala zibonelela ngeeparameter ezihlengahlengiswayo ngakumbi, zivumela abasebenzisi ukuba balungise kwaye benze ngokwezifiso iinkqubo zabo zeaudio ngokweemfuno zabo.

Isandisi-mandla se-Analog:Ii-Analog Power Amplifiers zihlala zineeparameter ezimbalwa ezihlengahlengiswayo, kwaye uhlengahlengiso lufezekiswa ikakhulu ngeesekethe zehardware. Ngenxa yoko, amandla ohlengahlengiso lwee-analog power amplifier alinganiselwe.

5. Imizekelo yesicelo

Isandisi-mandla seDijithali:IiDigital Power Amplifiers zifanelekile kwiinkqubo zeaudio ezifunwa kakhulu, ezifana neenkqubo zeaudio zobungcali, iaudio yesinema, kunye neaudio yeqonga. Ngenxa yokuchaneka kwazo okuphezulu kunye nokuguquguquka kwazo, ii-digital power amplifier zifumana usetyenziso olubanzi kwezi meko.

Isandisi-mandla se-Analog:Ii-Amplifiers ze-Analog Power zifanelekile kwiinkqubo zesandi zasekhaya ngokubanzi kunye nezixhobo zesandi ezincinci. Umgaqo wazo wokusebenza olula nothembekileyo unika iingenelo ezithile kwizicelo zesandi ezingabizi kakhulu.

Isiphelo

IiDijithali zamandla ombane kunye neeAnalog zamandla ombane ziintlobo ezimbini ezahlukeneyo zee-amplifier, ezibonisa umahluko ekucutshungulweni kwesignali yesandi, ukuchaneka, ukusebenza kakuhle, kunye neemeko zesicelo. Ukukhetha uhlobo lwe-amplifier olufanelekileyo ngokusekelwe kwiimfuno ezithile kunye nohlahlo-lwabiwo mali kunokuphucula kakhulu ukusebenza kwesandi kunye namava omsebenzisi kwinkqubo yesandi.
