The carrier frequency

網頁Description. carrSynch = comm.CarrierSynchronizer creates a System object that compensates for carrier frequency offset and phase offset in signals that use single-carrier modulation schemes. example. carrSynch = comm.CarrierSynchronizer (Name,Value) sets properties using one or more name-value pairs. 網頁In amplitude modulation, it is the voltage level of the signal to be transmitted that changes the amplitude of the carrier in proportion, see Figure 63.1. With no modulation, the AM carrier is transmitted by itself. When the modulating information signal (a sine wave) is applied, the carrier amplitude rises and falls in accordance.

載波（carrier wave）是指被調變以傳輸訊號的波形，一般為正弦波。一般要求正弦載波的頻率遠遠高於調變訊號的頻寬，否則會發生混疊，使傳輸訊號失真。 可以這樣理解，我們一般需要傳送的資料的頻率是低頻的，如果按照本身的資料的頻率來傳輸，不利於接收和同步。使用載波傳輸，我們可以將資料的訊號載入到載波的訊號上，接收方按照載波的頻率來接收資料訊號，有意義的訊號波的波幅與無意義的訊號的波幅是不同的，將這些訊號提取出來就是我們需要的資料訊號。 載 … 網頁2024年12月3日 · This is the MCQs in Analog Transmission from the book Data Communications and Networking by Behrouz A.
