第二天周六,天气天气晴好,起了个大早,因为LQ和版上著名滑雪诗人amplifier相约8:30在Solitude见面。一反前一
天早上的拖拉,大家展现了超高的效率,连带起床,BergerKing吃饭,开车,才8:20我们已经到了Solitude的Lodge.
清晨的雪场空旷宁静,几个lift刚刚运转起来。远处看几个山头蜿蜒并列,有点像缩小的Brenckenridge. 很快amplifier

p****i 发帖数: 5597 | 16 有个问题需要请教:
俺是纯外行,不过现在的工作需要用到超声,基本就是用FG产生信号,amplifier放大
,然后接到transducer。FG是一个EE的博士生设计的,amplifier是ENI 2100L,50db,
2手的
现在问题是:FG的信号设定是1V,1.5Mkz. Amplifier输出的应该的是316V,但是我观
测到的只有3V,如果amplifier的输出不连接任何cable,输出可以到67V,不过还是远
小于正常值。我同事已经用oscilloscope测出FG产生的信号正常。难道是amplifier的
问题?如果是的话如何检测呢?我们的这个transducer设计的是在1.5Mkz工作。
多谢大家的帮忙。 |
|
p****i 发帖数: 5597 | 17
我一开始试的100mv,输出基本是0, 但是频率变小的话到几十赫兹可以看到amplifier
的输出变大。但是我们这个设计是在超声的情况下运作。昨天用oscilloscope测了FG的
输出,都没有问题。会不会是因为接了有50db的amplifier后影响了FG的输出呢?主要
我们FG是自己弄的,amplifier花了3000刀买的,所以都是希望不要是amplifier的问题
。如果测试amplifier如何弄呢? |

q*******n 发帖数: 1334 | 22 我同意数字部分对音质不会有太大的影响。数字传输中即便存在bit error,jitter/
delay,大部分也都可以通过re-TX和在player那里加一个buffer解决。不同系统的音质
主要还是由音箱,DAC,和amplifier决定的。我个人的感觉是音箱的影响最大,DAC和
pre-amp次之,后级放大只要工作在线形区,保证一定程度的SNR,一般都没有什么问题

electronics.

Hifiman HM-801 vs. iPod, Zune: A sound winner?
Sure, iPods and Zunes can sound perfectly fine, but no one ever claimed they
were bona fide portable high-end audio devices. Their "good enough" sound

的档次里偶是满意了,当然升级之心不死。
