modulation

Yawning seems to be involved in the modulation of arousal process across the whole life span..打呵欠似乎与调整觉醒行为的过程有关，并伴随人的一生。

Its kinda analysis is based on some micro tremors in your voice, which is usually unheard by human ears that is able to form some kind of measurable modulation..它的分析是基于你声音中一些微小的颤动，这些颤动通常人耳是无法听到的，但是会形成一些可通过机器测量到的调制。

Contour modulation is a technique in which a phase-modulated signal waveform and amplifier output impedance work together to maintain higher efficiency over a sizable output power back-off..轮廓调制结合了一种相位调制信号的波形和放大器的输出阻抗，可在某个较大型输出电源关闭后保持更高的效率。
