A device that quantizes a signal applied to it.
1948Bell Syst. Techn. Jrnl. XXVII. 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. 1953Electronic Engin. XXV. 146/2 The channel modulators of a pulse-length modulated t.d.m. system feed a common quantizer and coder. 1967Electronics 6 Mar. 127/2 Sierra also offers a ‘quantizer’ that puts thermal contours..on the scope. 1975C. L. & J. W. S. Liu Linear Systems Analysis ii. 48 Consider a discrete quantizer whose output y(n) at any instant n is equal to the integral part of the input x(n) if the fractional part of x(n) is less than 0·5. |
