<standard> The <a href="">ITU-Ta> <a href="">standarda> for {nonuniform quantising logarithmic compression}. The equation for A-law is | A | ------- (m/mp) |m/mp| =< 1/A | 1+ln A y = | | sgn(m) | ------ (1 + ln A|m/mp|) 1/A =< |m/mp| =< 1 | 1+ln A Values of u=100 and 255, A=87.6, mp is the Peak message value, m is the current quantised message value. (The formulae get simpler if you substitute x for m/mp and sgn(x) for sgn(m); then -1 <= x <= 1.) Converting from <a href="">u-LAWa> to A-LAW introduces {quantising errors}. u-law is used in North America and Japan, and A-law is used in Europe and the rest of the world and international routes.

An A-law algorithm is a standard companding algorithm, used in European 8-bit PCM digital communications systems to optimize, i.e.
