在模擬電路和數(shù)字電路中，信號(hào)的表達(dá)方式不同。對(duì)模擬信號(hào)能夠執(zhí)行的操作，例如放大、濾波、限幅等，都可以對(duì)數(shù)字信號(hào)進(jìn)行操作。事實(shí)上，所有的數(shù)字電路從根本上來(lái)說(shuō)都是模擬電路，其基本電學(xué)原理，都與模擬電路相同?；パa(bǔ)式金屬氧化物半導(dǎo)體就是由兩個(gè)模擬的金屬氧化物半導(dǎo)體場(chǎng)效應(yīng)管構(gòu)成的，其對(duì)稱、互補(bǔ)的結(jié)構(gòu)，使它恰好能處理高低數(shù)字邏輯電平。不過(guò)，數(shù)字電路的設(shè)計(jì)目標(biāo)是用來(lái)處理數(shù)字信號(hào)，如果強(qiáng)行引入任意模擬信號(hào)而不進(jìn)行額外處理，則可能造成量化噪聲。設(shè)計(jì)的難度：模擬電路的設(shè)計(jì)通常比數(shù)字電路更為困難，對(duì)設(shè)計(jì)人員的水平要求更高。這也是數(shù)字電路系統(tǒng)比模擬電路系統(tǒng)更加普及的原因之一。模擬電路通常需要更多的手工運(yùn)算，其設(shè)計(jì)過(guò)程的自動(dòng)化程度低于數(shù)字電路。然而，數(shù)字式電子設(shè)備要在真實(shí)物理中得到應(yīng)用，就必須具有一個(gè)模擬的接口，因?yàn)樽匀唤绲拇蠖鄶?shù)實(shí)際信號(hào)是模擬的。例如，所有數(shù)字式收音機(jī)的信號(hào)接收器，都具有一個(gè)模擬的預(yù)放大器來(lái)進(jìn)行信號(hào)接收的步操作。
噪聲：在模擬電路中，由于信號(hào)幾乎完全將真實(shí)信號(hào)按比例表現(xiàn)為電壓或電流的形式，造成模擬電路對(duì)于噪聲的影響比數(shù)字電路更加敏感，信號(hào)的微小偏差都會(huì)表現(xiàn)為相當(dāng)顯著，造成信息損失。作為對(duì)比，數(shù)字電路只取決于高低電平，如果要造成信息傳遞的錯(cuò)誤，那么信號(hào)的偏差必須至少達(dá)到高電平的一半左右（具體的大小根據(jù)不同的電路規(guī)格有所不同）。因此，對(duì)信息進(jìn)行量化的數(shù)字電路對(duì)于噪聲的抵御能力比模擬電路更強(qiáng)，只要偏差不大于某一規(guī)定值，信息就不會(huì)損失。在數(shù)字電路中，噪聲在各個(gè)邏輯門的地方都可以得到消減。
