放大系數(Amplification Coefficient) 是電子工程和信號處理領域的一個核心參數,用于量化放大器或其他有源器件對輸入信號的增強能力。它本質上是輸出信號強度(如電壓、電流或功率)與輸入信號強度之間的比值,表征了器件對信號的放大程度。
放大系數(通常用符號 ( A ) 表示)的通用定義為: $$ A = frac{text{輸出信號量}}{text{輸入信號量}} $$ 根據放大對象的不同,可分為:
$$ AV = frac{V{out}}{V_{in}} $$
$$ AI = frac{I{out}}{I_{in}} $$
$$ AP = frac{P{out}}{P_{in}} $$
$$ text{Gain (dB)} = 20 log_{10}(AV) quad text{(電壓增益)} $$
$$ text{Gain (dB)} = 10 log{10}(A_P) quad text{(功率增益)} $$
放大系數是電子學基礎概念,在以下經典教材和行業标準中有詳細闡述:
amplification coefficient(放大系數)是一個技術術語,主要用于電子工程、物理學及工程學領域,表示系統或設備對輸入信號的放大能力。以下是詳細解釋:
在電子學中,電壓放大系數可表示為:
$$
Av = frac{V{text{out}}}{V_{text{in}}}
$$
其中,$Av$為電壓放大系數,$V{text{out}}$和$V_{text{in}}$分别為輸出與輸入電壓。
