Hfc is a kind of analog transmission technology , which is incompatible with the digital and optical trend of the entire telecom network Hfc屬于模擬傳輸技術(shù),與整個電信網(wǎng)絡(luò)的數(shù)字化、光纖化的發(fā)展趨勢不相吻合。
A functional unit that modulates and demodulates signals . one of the functions of a modem is to enable digital data to be transmitted over analog transmission facilities 一種對信號進行調(diào)制與解調(diào)的功能部件,調(diào)制解調(diào)器的功能之一就是使數(shù)字?jǐn)?shù)據(jù)經(jīng)由模擬傳輸設(shè)施進行傳送。
Analog (or analogue) transmission is a transmission method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. It could be the transfer of an analog source signal, using an analog modulation method such as Frequency modulation (FM) or Amplitude modulation (AM), or no modulation at all.
