“比特数”是这样一个单位,16比特就是指把波形的振幅划为2的16次方即65536个等级,根据模拟信号的轻响把它划分到某个等级中去,就可以用数字来表示了。和采样精度一样,波特率或比特率 越高,越能细致地反映乐曲的轻响变化。
转换比特数越大,性能价格比越高。
分析过程和结论,对于系统设计时量化比特数确定具有参考意义。
The analysis result and process are valuable for the decision of quantization bit number in the system design.
为了解码需要样品的宽度文件(比特数),和采样频率(赫兹),和本的信道数。
In order to decode the file you need the width of the samples (number of bits), and the sampling frequency (Hertz), and the number of channels present.
And so when we say something is exponential, we're talking about in terms of the number of bits required to represent it.
所以当我们说某些东西,是指数增长的我们指的,就是代表它的比特数。
And just to plant this seed with 32 bits, what's the biggest number you can represent?
而对于32比特,所能表示的最大的数是多少?
to the n, every value in the 1 bit vector we looked at last time is either 0 or 1. So it's a binary n number of n bits, 2 to the n.
从2到n,我们上次看到的,位向量的每个值不是0就是,所以它是n,比特的二进制数,从2到。
