其次,“黄金律法”告诉我们,只要音频信号在听阈内,两倍采样点就足够在DA过程中完美还原它的听感了,再多的采样点只是效果一致的资源浪费(相关概念见上一篇文章,Nyquist Frequency/BandWidth/Anti-Aliasing Filter/DA过程中的数学最优解) 即使DA过程可以还原,大部分民用设备也无法播放超过一定频率范围的声音 虽然,研究表...

In order to do so reliably, the signal must have limited bandwidth—its frequency components must be no greater than some known frequency fc. We must then sample the signal at a minimum rate known as the Nyquist rate. Fig. 6.1 shows a sinusoidal signal and samples taken at two different ...

It has to be noted that even if the concept of "twice the highest frequency" is the more commonly used idea, it is not absolute. In fact the theorem stand for "twice the bandwidth", which is totally different. Bandwidth is related with the range between the first frequency and the last...
