Frequency modulation and amplitude modulation are still with us to this day, but now these modulation methods are used to send digital data at high speeds over a high frequency carrier wave. Technologies like 802.11 standards (a.k.a. WiFi) use amplitude modulation while other radio technologie...
AM has the advantage of simplicity, but it is not the most efficient mode to use – both in terms of the amount of spectrum it takes up and the usage of the power. For this reason, it is rarely used for communications purposes. Its only major communications use is for VHF aircraft ...

又由于工质在蒸发时微结构可以产生毛细力, 所以均热板的运作可不受重力的影响。 均热板与热管的原理与理论架构是相同的,只有热传导的方式不相同,热管的热传导方式是一维的,是线的热传导方式,而 均热板的热传导方式是二维的,是面的热传导方式。 收藏 分享 下载 举报 用客户端打开 ...

over a distance is usually performed by operating on one of the characteristics of a radio frequency wave. This wave, known as the carrier, will originally be sinusoidal with constant amplitude and frequency. It is these two characteristics which are affected by the modulation processes, as will...
