Description: pcm均匀pcm与非均匀pcm
一。产生长度为500的零均值，单位方差的高斯随机变量序列，用均匀pcm的方法用16电平进行量化：1）求所得的SQNR，该序列的前5个值，相应的量化值和相应的码字。2）画出量化误差（定义为输入值和量化值之间的差），同时 画出量化值作为输入值的函数的图。3）用128量化电平数重做2）题， 比较结果。-pcm uniform pcm with a non-uniform pcm. Have a length of 500 zero-mean, unit variance Gaussian random variables with a uniform method of pcm level by 16 to quantify: 1) demand from SQNR, the sequence of the first five values, the corresponding quantization value and the corresponding code word. 2) draw quantization error (defined as the import value and quantify the value of the difference between), at the same time draw to quantify the value of the import value as a function of the map. 3) 128 to quantify the number of redo-level 2) title, the results of the comparison.
