律u律pcm编码

若输入A律PCM编码器的正弦信号为x(t)=sin(1600πt),采样序列为x(n)=sin(0.2πn),n=0,1,2,…,10，将其进行PCM编码，求出编码器的输出码组序列y(n)。

要求：1) 直接采用A律扩展器函数求解上述问题。

2）使用13折线法近似A律PCM 求解上述问题。

3）计算量化误差。-Law a law pcm coding

If the input A-law PCM encoder is sinusoidal signal x (t) = sin (1600πt), for the sample sequence x (n) = sin (0.2πn), n = 0,1,2, ..., 10, it will be PCM coding to obtain the coded output code group sequence y (n).

Requirements: 1) directly　A-law expander function to solve the above problems.

2) using a 13 fold line approximation A-law PCM to solve the above problems.

3) calculating the quantization error.
