<Standard> The ITU-T Standard 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 u-LAW 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.
