1. The analog signals are transmitted over common wire to the demodulator, which convert them into digital signals. 模拟信号通过普通电话线传送到解调器上,解调器又将其转换成数字信号。
2. Typically, both the modulator and demodulator section of the converter are combined into a two-way data transmitter_receiver, commonly called a data modem or data set . 一般而言,数据转换部分的调制和解调部分组合成收发两路信号,我们通常称之为数据调制解调器或数据传输机。
3. Modem (Modulator/Demodulator): A device that converts a digital signal to an analog signal and vice-versa, and often used to communicate signals from a telephone line to a computer. 调制解调器:把数字信号转为模拟信号或相反情况的装置。常用于在电话线内传送信号往电脑。
