Listening radio with grass
推荐理由
AM radio is such a simple modulation scheme that even a piece of grass can be used to demodulate it, with enough power.
说明
这是2012年由ateijeiro0发布的一部演示,主题归在Electronics & circuit design。它讲的是AM radio demodulation这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Two experimenters hold blades of grass near a radio transmitter antenna and hear the AM station through the arc between antenna and grass. It is a short, informal demonstration of unintentional AM demodulation.这些读者给出的理由,核心是:HN commenters bring it out whenever AM radio, strong transmitters or accidental demodulation comes up, as the classic example of grass playing radio.讲法不绑某一条新闻,过几年仍然可以当材料看。从2017年到2026年,有0位不同的读者在0个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义,就把注意力放在它怎么把AM radio demodulation变成能跟着复述的例子。
