Abstract:
The digital-to-analog converters (DAC) are widely applied for transformation of signals in an informational - measurement technology, radio engineering and instrument making. They are a potent resort of increase readout accuracy. However existing a DAC can execute only linear transformation of a kind Uout = k Uref. At the same time in different areas of engineering it is necessary with a split-hair accuracy to replicate non-linear functional connections. For example, such necessity arises at construction digital-controlled of phase changes and calibrators of a phase, as the relation of a phase shift to change of a controlled variable is always non-linear. The most preferential way for implementation of this operation - usage a DAC.
