今天突然想到:相同阻值的电阻先串联再并联,N后阻值为多少?
今天突然想到很早之前在论坛里看到过的一个帖子,由@maychang 老师解释过的,但是找了半天了一直找不到那个原来的帖子了,只好再新发一个, 问题是这样的:相同阻值的电阻先串联再并联,N后阻值为多少?如下图所示,使用阻值为1欧的电阻不断的串联、并联,N级后阻值是多少? 如果是5级以内,通过串并联公式也能慢慢算出来,这是最原始的办法,超过5级后再这样计算会很复杂,大家有没有更好的分析方法

TI CC2640R2F献给初学者的文档
     程序是什么?程序就是个流程,很多人对着协议栈,不知道从哪下手,然后哪里出了问题也不知道怎么改,提出问题,别人说原理,又觉得自己用不上,实际上,原理就是流程,顺着原理去读程序,就很顺畅。 先解释几个基本点: 一、低功耗的思路。这个概念,很多人不懂,先解释这个,懂了这个,BLE很多事情就清晰很多。 人的低功耗,就是躺着比走路省卡路里,走路比跑步省卡路里。这个很容易懂吧? 然后切换到芯
