Abstract:
A method of activating a binary controllable transducer in correspondence with an N-bit data value A representing a physical value D by converting a digital signal representative of said N-bit value into a binary signal that, when applied to said transducer under control of a strobe signal, causes said physical value D to be generated, the method comprising the steps of:(i) converting said N-bit data value A from said physical value D into a linear combination ##EQU3## of P values A.sub.i, P being greater than or equal to 2 and being smaller than N, wherein a predefined time step t.sub.i corresponds to each of said values A.sub.i, and(ii) converting said digital signal into said binary signal that is active during a period t.sub.on, wherein t.sub.on is equal to ##EQU4##
