時域測量與頻域測量 測量被測對象在不同時間的特性，即把它看成是一個時間的函數f(t)來測量，稱為時域測量。例如，對圖中a的信號 f(t)可以用示波器顯示并測量它的幅度、寬度、上升和下降時間等參數。把信號f(t)輸入一個網絡，測量出其輸出信號f(t)，與輸入相比較而求得網絡的傳遞函數h(t)。這些都屬于時域測量。 對同一個被測對象，也可以測量它在不同頻率時的特性，亦即把它看成是一個頻率的函數S(ω)來測量，這稱為頻域測量。例如，對信號f(t)可以用頻譜分析儀顯示并測量它在不同頻率的功率分布譜S(ω)，如圖b。把這個信號輸入一個網絡,測量出其輸出頻譜S′(ω)，與輸入相比較而求得網絡的頻率響應G（ω）。這些都屬于頻域測量。用一個頻率可變的正弦（單頻）信號作輸入，測量出在不同頻率時網絡輸出與輸入功率之比，也得到G(ω)。這仍然是頻域測量。 時域與頻域過程或響應，在數學上彼此是一對相互的傅里葉變換關系 這里*表示卷積。時域測量與頻域測量互相之間有唯一的對應關系。在這一個域進行測量，通過換算可求得另一個域的結果。在實際測量中，兩種方法各有其適用范圍和相應的測量儀器。示波器是時域測量常用的儀器，便于測量信號波形參數、相?還叵島褪奔涔叵檔取?頻譜分析儀是頻域測量常用的儀器，便于測量頻譜、諧波、失真、交調等。
