An equation used as a T1 standard that describes the non-linear compression performed in the analog-to-digital conversion process of PCM systems used in the USA, Canada, and Japan.

Mu-Law and A-Law are Pulse Code Modulation (PCM) techniques that dictate forms of compression for audio signals. They are widely-used standard methods of coding voice as they improve the signal-to-noise ratio without increasing the amount of data. Mu-Law is a standard in North America; A-Law in Europe.

See "U-Law" below.

Not an acronym. Pronounced `mew-LAW' - the `Mu' is actually the Greek letter `Mu'. An 8-Bit compression code for audio signals including speech. It is widely used in the telecommunications field because it improves the signal-to-noise ratio without increasing the amount of data. It is a companding technique. That means it carries more information about the smaller signals than the larger. Sometimes appears in documents written as `ULAW'.

The PCM coding and companding standard used in Japan and North America (T-1 areas).

(1) A pulse-code modulation (PCM) algorithm used in digitizing telephone audio signals in T-1 areas. (2) The PCM coding and compounding standard used in Japan and North America.

North American companding standard used in conversion between analog and digital signals in PCM systems. Similar to the European a-law. See also a-law and companding.

The North America and Japan standard for nonuniform quantising logarithmic compression.

One of two algorithms used in telephony to logarithmically compress or expand digitized speech. mu-law is used in North America and Japan. A-law is the other algorithm used in European networks. See also A-law.

A TI standard algorithm that describes the nonlinear compression performed in the analog-to-digital conversion process of PCM systems used in the USA, Canada, and Japan. See A-law.

The PCM voice coding and companding standard used in Japan and North America. A PCM algorithm yielding a raw 64-kbps transmission rate.
