In practice for the decision of a task of increase the accuracy of process of analog-digital transformation, use only precision АDC, in perfection and which creation the modern firms - developers of electronic components are engaged. However, it completely does not decide the put task for several reasons. First, high accuracy of the characteristic АDC yet are not a guarantee that in conditions of influence external damage of the factors, at which equipment given АDC all also usually works will be exact. Secondly, the process of analog-digital transformation is complex and provides besides the basic operation of analog-digital transformation which is carried out АDC, also performance of a number of necessary accompanying operations substantially determining accuracy of transformation in whole. It is operations previous to analog-digital transformation: samples and storages of entrance signals АDC, formation of absolute meaning of entrance bipolar signals АDC; and subsequent operation of correction of errors АDC.
However, neither in the technical literature, nor among the developers, to these operations (subsystems) is not given of sufficient attention. This testifies to necessity of realization of additional researches for this area. Therefore on our sight, the task of increase of accuracy of process of analog-digital transformation should be reduced not only to perfection of integrated microcircuits which are carrying out transformation, but also to complex increase of accuracy of process of analog-digital transformation, in view of subsystems, included in him. We are engaged with development of methods and devices of their realization directed on increase to accuracy of operations of analog-digital transformation.
