quantise
     v 1: telecommunications: approximate (a signal varying
          continuously in amplitude) by one whose amplitude is
          restricted to a prescribed set of discrete values [syn:
          {quantize}]
     2: apply quantum theory to; restrict the number of possible
        values of (a quantity) or states of (a physical entity or
        system) so that certain variables can assume only certain
        discrete magnitudes that are integral multiples of a
        common factor; "Quantize gravity" [syn: {quantize}]
