靜電(dian)感應（指(zhi)電(dian)的(de)(de)耦合）。靜電(dian)感應是兩電(dian)場(chang)相(xiang)互作用的(de)(de)結果。在相(xiang)對的(de)(de)兩根導(dao)線中，如其一的(de)(de)電(dian)位(wei)發生變化(hua)，則由于導(dao)線間的(de)(de)電(dian)容變化(hua)使得另一導(dao)線的(de)(de)電(dian)位(wei)也發生變化(hua)，干擾源以電(dian)容性的(de)(de)耦合在回路(lu)中形成干擾。

3、附加熱電勢(shi)和化學電勢(shi)。由(you)于(yu)不同金屬產生的熱電勢(shi)以及金屬腐蝕等產生的化學電勢(shi)，在電路回路中(zhong)形成直(zhi)流電氣干擾。

4、振(zhen)動。在(zai)強振(zhen)動的環境中，導線(xian)由于(yu)(yu)在(zai)磁場中處于(yu)(yu)運動狀態而產生(sheng)感應(ying)電勢，此干(gan)擾(rao)與信號相串聯(lian)，以串模干(gan)擾(rao)形式進入儀器儀表(biao)。

5、不同(tong)地電位引入(ru)的(de)干擾(rao)。在(zai)(zai)大功率的(de)用(yong)電設備附近，當(dang)設備的(de)絕緣性(xing)能較差(cha)時，不同(tong)地電位的(de)電位差(cha)的(de)引入(ru)形(xing)(xing)成干擾(rao)，而在(zai)(zai)儀(yi)(yi)(yi)表(biao)的(de)使用(yong)中往(wang)往(wang)會(hui)(hui)有意無(wu)意地使輸入(ru)端存在(zai)(zai)兩個(ge)以上(shang)的(de)連接(jie)點，這樣就會(hui)(hui)把不同(tong)接(jie)地點的(de)電位差(cha)以共模干擾(rao)形(xing)(xing)式引入(ru)到儀(yi)(yi)(yi)器儀(yi)(yi)(yi)表(biao)，這種干擾(rao)是同(tong)時出現在(zai)(zai)兩信號線上(shang)的(de)。

6、信(xin)(xin)號源是不平衡電(dian)(dian)(dian)橋(qiao)。當(dang)橋(qiao)路(lu)電(dian)(dian)(dian)源接(jie)地時(shi)，除橋(qiao)路(lu)對角線(xian)的不平衡電(dian)(dian)(dian)壓（即信(xin)(xin)號電(dian)(dian)(dian)壓）外，兩信(xin)(xin)號線(xian)對地都有一個公(gong)共的共模干擾(rao)電(dian)(dian)(dian)壓。雖然共模干擾(rao)不和信(xin)(xin)號疊(die)加，不直接(jie)對儀表產生(sheng)影響(xiang)，但它能通過測量系統(tong)形成(cheng)到(dao)地的漏電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)，通過電(dian)(dian)(dian)阻的耦合(he)就(jiu)能直接(jie)作用于(yu)儀表（或放大器），產生(sheng)干擾(rao)。

7、一些脈沖狀的干擾電壓除能作用于模擬電路外，有時也能直接進入數字電路中給予干擾，這些干擾電壓的發生源是開關、電機、繼電器那樣的感性負載和產生放電的機器等。
