描述
通信就是把信息從一個地方傳遞到另一個地方。這包括許多形式的信息,例如:電話交談,電視信號,計算機(jī)文件以及其他類型的數(shù)據(jù)。要在兩地之間傳遞信息,你需要一個連接兩地的通道,而這個通道也可能是雙絞線,無線電,光纖等形式中的一種。電信公司花錢建立和維護(hù)這些通道,然后通過給他們的客戶傳送信息來獲利。并且單一通道傳遞的信息越多,他們就越賺錢。數(shù)字信號處理已經(jīng)徹底改變了通信的許多領(lǐng)域,用它可以進(jìn)行信號音的產(chǎn)生和檢測、頻帶移動、濾除電源線的噪音等等。下面就來看一下電信網(wǎng)絡(luò)中數(shù)字信號處理兩個典型的應(yīng)用:多路復(fù)用、數(shù)據(jù)壓縮。
