A facsimile of the original amplifier outputs is then reconstructed inside the computer . 一個(gè)放大器原來輸出的復(fù)制品就送到處理裝置中去。
Third , rail - to - rail amplifier output stages exhibit load - dependent gain which affects amplifier open - loop gain , and hence closed - loop gain accuracy 第三,軌到軌放大器輸出級(jí)增益與負(fù)載有關(guān),這將影響放大器的開環(huán)增益,當(dāng)然也影響了閉環(huán)增益的準(zhǔn)確性。
If the speaker needs more current ( its overall impedance drops ) then a lower amplifier output impedance will allow that current to be drawn out of the amplifier without causing much of a change in the applied voltage - and that means less distortion 如果揚(yáng)聲器需要更大電流(揚(yáng)聲器的整體阻抗降低) ,那么一個(gè)低輸出阻抗的放大器可以容許在輸出相應(yīng)電流的同時(shí),所施加的電壓變化更小,這也意味著失真更小。
