ABSTRAKT

Consideration was given to the problems of constructing analog-to-digital (AD) systems for highly linear forward and reverse converter of analog signals, and also the main approaches to constructing AD systems, their advantages and limitations being detected. There was offered the method for designing the information form converters whose parts are digital-to-analog converters (DAC) with weight redundancy that allowed us to create AD systems without laser adjustment of elements parameters and therewith to have high static and dynamic characteristics. There were presented the analytical relations confirming the prospects of the offered approaches, the computer simulation of DAC operation with an active filter based on the direct current amplifier (DCA) was carried out, and the recommendations on determining the optimal values of filter parameters were given.
