Description: 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.
