?一:baseband是什么意思(中英文)解釋的意思
Baseband是指數(shù)字通信中用于傳輸原始信號的頻帶,也可以理解為基帶信號。它是指未經(jīng)過調(diào)制的信號,通常是低頻信號,音頻、視頻等。在無線通信中,baseband也可以指代數(shù)字調(diào)制解調(diào)器或基站器。
英文釋義:Baseband refers to the frequency band used for transmitting raw signals in digital communication, or the baseband signal. It refers to the unmodulated signal, usually a low-frequency signal such as audio, video, etc. In wireless communication, baseband can also refer to digital modems or base station controllers.
[?be?s?b?nd]
Baseband通常用于數(shù)字通信領(lǐng)域,如無線電、網(wǎng)絡(luò)等。它可以作為一個名詞使用,也可以作為一個形容詞修飾其他名詞。
1. The baseband signal is transmitted through a physical medium.
2. The base station controller is responsible for managing the baseband processing.
3. The audio data is converted into a digital baseband signal before transmission.
4. The modem uses a baseband processor to convert the digital signals into analog signals.
調(diào)制解調(diào)器使用基帶處理器將數(shù)字信號轉(zhuǎn)換成模擬信號。
5. The baseband frequency range is usually between 0 Hz and 20 kHz.
基帶頻率范圍通常在0 Hz至20 kHz之間。
1. Low-pass signal: 低通信號,與baseband相似,指未經(jīng)過調(diào)制的信號。
2. Unmodulated signal: 未調(diào)制信號,與baseband含義相同,指原始信號。
3. Digital baseband: 數(shù)字基帶,指數(shù)字化的原始信號。
4. Baseband processing: 基帶處理,指對原始信號進(jìn)行處理的過程。
5. Base station controller: 基站器,負(fù)責(zé)管理基帶處理和無線通信的設(shè)備。
Baseband是一個重要的概念,在數(shù)字通信領(lǐng)域有著廣泛的應(yīng)用。它可以理解為傳輸原始信息的頻帶或者未經(jīng)過調(diào)制的信號。在無線通信中起著關(guān)鍵作用,通過數(shù)字調(diào)制解調(diào)器將數(shù)字信息轉(zhuǎn)換成模擬信號進(jìn)行傳輸。我們需要深入了解baseband的概念和用法,以便更好地理解數(shù)字通信技術(shù)。
