提醒大家,标题问题的严重性。楼主请尽快修改成合格的标题。
诶我上午看这个帖子还不是这样啊!我已经改好了。 也许是电脑中毒了 上午标题挂在这里等回复的时候被修改了! 让各位见笑了 {:sweat:} fusakayuk 发表于 2014-11-10 16:10
要用专门的DA转换芯片才能转成模拟信息,PCM转模拟可以用ESS9018。
谢谢 我看看这个芯片资料去 gzhuli 发表于 2014-11-11 14:53
简单来说就是把PDM送进一个数字低通滤波器做降采样,出来就是PCM了。
降采样最常用的数字滤波器是CIC滤波器 ...
谢谢!看了您的话感觉就是这样~! linxiaoutziCCCP 发表于 2014-11-11 11:47
我承认我是被标题吸引来的,首先,你得列出你学姐的QQ号,然后我们才能问她这个型号是什么···
这个网站我也找到了 ,但是对于滤波这类的知识不是很明白,所以才问各位大大 咦,标题改回来了 刚煜 发表于 2014-11-11 15:36

不是电脑中毒了,是你的标题不符合论坛规矩
http://www.amobbs.com/thread-5511230-1-1.html 楼主还不快改回合格的标题等会莫大又会帮你改了。{:lol:} 刚煜 发表于 2014-11-11 15:43

是音频滤波处理吧,如果不熟悉又想用,可考虑用ADI的专用音频处理器····
RE: 关于PCM和PDM信号
armok 发表于 2014-11-11 15:59楼主,“关于PCM和PDM信号”这个标题仍不合格!
现在我想改成 : 如何把数字麦克风输出的PDM信号转换成PCM信号 现在好像改不了标题了!=。= linxiaoutziCCCP 发表于 2014-11-11 16:48

哪需要ADI这么高大上的东西,白菜STM32就行,直接有官方库。 Arrowzhang 发表于 2014-11-11 16:21

嗯 听说407有现成的库可以用 armok 发表于 2014-11-13 10:29
楼主的标题“关于PCM和PDM信号” 仍是不合格。难道真的只能封锁ID?
大概是时间过了,修改不了标题了 大师一语中的!PDM脉冲编码输出是1bit数据流,类似∑-△ADC的调制器 lz可搜索这方面的文献,一般用CIC和FIR滤波器,另 stm32有PDMlib 很好使 .syntax unified
