f****i 发帖数: 20252 | 29 跟那个1kHz tone没关系,1kHz tone是用来测harmonic distortion的
连续信号离散化的时候,timing的误差变化算是jitter
离散信号数字化的时候,振幅的误差变化是ADC/DAC round offer error
你说的这个问题可以通过提高DAC的位数来减小 |
|
z*****n 发帖数: 7639 | 30 看来这儿对jitter的误解还真多!
jitter是指的时钟误差,这个我当然知道。
不过对于音频设备,最后看啥结果?还不是
看你的输入音频和输出的差别有多大?
数字信号的方波会出现上升/下降沿的时钟
不齐问题,一个模拟正弦波信号还不是会
出现同样的问题?实际上传输通道都是低通
滤波器,方波进去出来都是前面几个harmonics。
我的意思很明白,cd采样本身就造成jitter,
一个正弦波经过这么一番折腾,出来的时候
过零点的周期都是变化的。 |

扬声器本身要考虑的设计因素很多,hall effect,faraday induction,cooling,
damping,harmonics等等。所以一个在业内积累了很长时间的老厂,要比新的hifi厂家
有更大的技术优势。而且制造过程中很多都是emprical的,长期下来就形成了自己的风
格。一般人们所说的好推不好推也都是相对于品牌之间的比较,可能都很“好推”,只
是一个喇叭比另外一个更容易达到最佳工作状态,如果非要定一个标准,88dB以上灵敏
度的音箱,都是比较“好推”的类型。
在放大器方面,root mean square (RMS)rating也是参考的一个指标,对于乙类和甲
乙类,可以参考:

瞬态响应也很重要,不同的电路特点不一样,甲类肯定是最好的。更详细的,去图书馆
