中文百科

调制

调制是一种将一个或多个周期性的载波混入想发送之信号的技术,常用于无线电波的传播与通信、利用电话线的数据通信等各方面。依调制信号的不同,可区分为数字调制及模拟调制,这些不同的调制,是以不同的方法,将信号和载波合成的技术。调制的逆过程叫做解调,用以解出原始的信号。

英语百科

Modulation 调变

A low-frequency message signal (top) may be carried by an AM or FM radio wave.
Schematic of 4 baud (8 bit/s) data link containing arbitrarily chosen values.

In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.

In telecommunications, modulation is the process of conveying a message signal, for example a digital bit stream or an analog audio signal, inside another signal that can be physically transmitted. Modulation of a sine waveform transforms a baseband message signal into a passband signal.
