{modulation}, {pitch contour}]
4: a manner of speaking in which the loudness or pitch or tone

may be, by successive changes, into a key quite remote.
There are also sudden and unprepared modulations.
[1913 Webster]

4. (Electronics) The alteration of hte amplitude, intensity,
frequency, or phase (of the carrier wave of a radio
signal) at intervals, so as to represent information to be
transmitted.

  • 调变 - 百度百科
    调变（modulation），中文又称调制，是通信技术中将信号与周期性载波合成的关键技术，其逆过程称为解调。 该技术通过频谱搬移使信号适应传输需求，例如将低频语音信号调制到高频以缩减天线尺寸，同时实现多路复用避免信号干扰。
  • 什么是调制（modulation） ?-CSDN博客
    调制定义： 调制是通过向 电子或光载波信号 添加信息 将数据 转换为 无线电波 的过程。 载波信号是具有稳定波形的信号——具有恒定的 幅度和频率。 调制的工作原理 信息可以通过改变其振幅、 频率 、相位、 偏振 （对于光信号）甚至量子级现象 来添加到载体中 。 调制通常应用于电磁信号
