1948 Bell Syst. Techn. Jrnl. 27 450 An actual quantizer (staircase transducer) has a finite overload value which must not be exceeded and hence can have only a finite number of steps.
1953 Electronic Engin. 25 146/2 The channel modulators of a pulse-length modulated t.d.m. system feed a common quantizer and coder.
1992 IEEE Spectrum Mar. 27/1 MPEG also uses visually weighted quantization—that is, coarser quantizers can be used for the higher frequencies because subjective perception of quantization error varies greatly with frequency.
2005 W.-H. Steeb Math. Tools Signal Processing with C++ & JAVA Simulations x. 164 The pitch period is quantised using a log companded quantiser to one of 60 possible values.
