[Other resource] LawAgrith DL : 0: The µ -law algorithm (pronounced myoo-law) is a companding algorithm, primarily used in the digital telecommunication systems of North America and Japan. As with other companding algorithms, its purpose is to reduce the dynamic range of an audio signal. In the analog domain, this can increase the signal-to-noise ratio (SNR) achieved during transmission, and in the digital domain, it can reduce the quantization error (hence increasing signal to quantization noise ratio). These SNR increases can be traded instead for reduced bandwidth for equivalent SNR.

[Other] ulawcompander.m DL : 0: Companding is essentially a technique for achieving non-uniform quantization. There are basically 2 methods which are most popular in literature.:-A-law companding and u-law companding. These algorithms help in achieving to an extend, compression. The given code shows how to compress a 14-bit code to 8-bit code and its digital implementation using matlab. Please contact by mail if a detailed description of code is needed.

[DSP program] DSP_Lab_070 DL : 0: For a file(.wave) • Find the sampling frequency and the number of bits per sample. • Re-quantize the samples using the following methods: o Linear Quantization o A-Law Companding with A=87.6 o μ-Law Companding with μ=255 • Use a mid-rise quantizer with 4, 5, 6, 7, and 8 bits per sample. • Obtain the signal-to-quantization noise ratio (SQNR) for each of the above 15 cases. • It is required to plot the SQNR (dB) versus the number of bits per sample for linear quantization, A-law companding, and μ-law companding. All 3 plots may be on the same figure, if convenient. -For a file(.wave) • Find the sampling frequency and the number of bits per sample. • Re-quantize the samples using the following methods: o Linear Quantization o A-Law Companding with A=87.6 o μ-Law Companding with μ=255 • Use a mid-rise quantizer with 4, 5, 6, 7, and 8 bits per sample. • Obtain the signal-to-quantization noise ratio (SQNR) for each of the above 15 cases. • It is required to plot the SQNR (dB) versus the number of bits per sample for linear quantization, A-law companding, and μ-law companding.

The binary representation of time discrete, amplitude discrete and quantized signals is completed respectively. According to CCITT, in order to improve the performance of small signal quantization, using companding non-uniform quantization, there are two suggestions, respectively A law and the law of our country, using the A law, the A law compression complex, often using 13 line method for encoding, using non uniform quantization coding PCM.)
