Groshev UDC 621.3. 087.92 The functional analog-to-digital converter (FADC) described in [I] allows direct entry of a required linearization function by sampling values of the measured parameters. Unfortu- nately, simplicity of construction -- the principal advantage of this circuit -- limits its functional capabilities. In particular, the employed linearization algorithm only allows piecewise-linear approximation on one of the outside intervals with direct programming by "standards" which significantly reduces the accuracy of measurement in the given interval, makes it impossible to output the results in the measured-quantity units, etc. Moreover, the programming technique proposed in [i] is based on using a set of "standards" with a fixed increment of the measured quantity which is difficult or even impossible to realize for many physical parameters. This markedly limits the field of reprogrammable FADCs. Here we propose a functional analog-to-digital converter whose capabilities and field of application have been significantly extended both by selecting a more universal lineariza- tion algorithm and by using a more flexible programming technique. A simplified circuit diagram of the device is shown in Fig. i. The functional converter includes a linear dual-slope integration analog-to-digital converter (DIADC) with direct read- out which has been slightly modified.
